| − | ===Dilution===
| |
| | | | |
| − | (including PIDs) | + | The HFI instrument is designed around 52 bolometers. Twenty of the bolometers (spider-web bolometers or SWBs) are sensitive to total power, and the remaining 32 units are arranged in pairs of orthogonally-oriented polarisation-sensitive bolometers (PSBs). All bolometers are operated at a temperature of ~0.1 K by means of a space qualified dilution cooler coupled to a high precision temperature control system. A 4He-JT system provides active cooling for 4 K stages using vibration controlled mechanical compressors to prevent excessive warming of the 100 mK stage and minimize microphonic effects in the bolometers. Bolometers and sensitive thermometers are read using an AC-bias scheme through JFET amplifiers operated at ~130 K that provide high sensitivity and low frequency stability. The HFI covers six bands centred at 100, 143, 217, 353, 545, and 857 GHz, thanks to a thermo-optical design consisting of three corrugated horns and a set of compact reflective filters and lenses at cryogenic temperatures. |

The various parts of the HFI are distributed among three different stages of the satellite in order to provide each sub-system with an optimal operating temperature. The "warm" parts, including nearly all the electronics and the sources of fluids of the 4K and 0.1K coolers, are attached and thermally linked to the service module of the satellite. The first stage of the preamplifiers is attached to the back of the passively cooled telescope structure. The focal plane unit is attached to the 20K stage cooled by the sorption cooler.

| + | The telescope and horns select the geometrical origin of photons. They provide a high transmission efficiency to photons inside the main beam, while photons coming from the intermediate and far-side lobes have very low probability of being detected.

| + | Since the bolometer thermometer is part of an active circuit that also heats it, the response of this system is complex and has to be considered as a whole. In addition, due to the modulation of the bias current and to the sampling of the data, the response signal of the instrument when scanning a point source is more complex still. Item in Sub-Section [[HFI_detection_chain#Time_response|Time_response]] and Annex [[HFI_time_response_model]] are dedicated to the description of this time response. |

| − | The heart of the HFI - the detectors - are bolometers, solid-state devices in which the
| |
| − | incoming radiation dissipates its energy as heat that increases the temperature of a
| |
| − | thermometer. The instrument Flight Model total number of bolometers is 52, split into 6
| |
| − | channels at central frequencies of 100, 143, 217, 353, 545, and 857GHz.
| |
| − | | |
| − | Thirty two of these bolometers are polarization sensitive allowing a map of the CMB polarisation to be built.
| |
| − | | |
| − | | |
| − | | |
| − | Bolometers consist of (i) an absorber that transforms the in-coming radiation into heat; (ii) a thermometer that is thermally linked to the absorber and measures the temperature changes; and (iii) a weak thermal link to a thermal sink, to which the bolometer is attached.
| |
| − | | |
| − | | |
| − | The detectors are semi-conducting NTD thermistor bolometers. There are two kinds of detector modules:
| |
| − | | |
| − | * SWB, spider web bolometers, are mounted on an absorbing spider-web of metallised silicon nitride
| |
| − | * PSB, polarization sensitive bolometers, are mounted or on a parallel absorbing grid of metallised silicon nitride.
| |
| − | | |
| − | | |
| − | In the spider-web bolometers, or SWBs (Bock et al. 1995; Mauskopf et al. 1997), the absorbers consist of metallic grids
| |
| − | deposited on a Si3 N4 substrate in the shape of a spider web.
| |
| − | The mesh design and the impedance of the metallic layer are
| |
| − | adjusted to match vacuum impedance and maximize the absorption of millimeter waves, while minimizing the cross section to
| |
| − | particles. The absorber is designed to offer equal impedance to
| |
| − | any linearly polarised radiation. Nevertheless, the thermometer
| |
| − | and its electrical leads define a privileged orientation (Fig. SWB) that
| |
| − | makes the SWBs slightly sensitive to polarisation, as detailed in
| |
| − | (Rosset et al. 2010). The thermometers are
| |
| − | made of neutron transmuted doped (NTD) germanium (Haller
| |
| − | et al. 1996), chosen to have an impedance of about 10 MΩ at

| − | The absorber of PSBs is a rectangular grid (Fig. PSB) with metallization in one direction (Jones et al.
| |
| − | 2003). Electrical fields parallel to this direction develop currents and then deposit some power in the grid, while perpendicular electrical fields propagate through the grid without significant interaction. A second PSB perpendicular to the first one absorbs the other polarisation. Such a PSB pair measures two polarisations of radiation collected by the same horns and filtered by the same devices, which minimises the systematic effects: differences between polarised
| |
| − | beams collected by a given horn are typically less than −30 dB of
| |
| − | the peak. The differences in the spectral responses of a PSB pair
| |
| − | also proved to be a few percent in the worst case. Each pair

| − | | |
| − | This section may also go somewhere else, like in optics
| |
| − | | |
| − | The layout of the detectors in the focal plane is defined to cope with the
| |
| − | scanning strategy. The HFI horns are positioned at the centre of the focal plane, where the optical
| |
| − | quality is good enough for the high frequencies. The curvature of
| |
| − | rows compensates for the distortion of images by the telescope.
| |
| − | A pair of identical SWB will scan the same circle on the sky to
| |
| − | provide additional redundancy. Similar horns feeding PSBs are
| |
| − | also aligned so that two pairs of PSBs rotated by 45◦ with respect to each other scan the same line. This will provide the Q and U Stokes parameters with minimal correction for the pointing (Rosset et al. 2010). Residual systematics will come from the differences between the beam shapes of the two horns. In all
| |
| − | cases except for the 100 GHz horns, a measurement is also done
| |
| − | by a pair of similar channels shifted by 1.25 arcminutes in the cross-scan direction, to ensure adequate sampling. In the figures focal plane layout is reported.

| |
| − | The AC bias readout electronics of the HFI instrument (Gaertner et al. 1997) includes a number of original features proposed by several laboratories (CRTBT in Grenoble, CESR in Toulouse and IAS in Orsay), which were validated on the Diabolo experiment and on the balloon-borne Archeops experiment. It was developped for space by the CESR in Toulouse.
| |
| − | | |
| − | | |
| − | The particular features of the HFI AC bias readout are mainly
| |
| − | | |
| − | | |
| − | * i)that the cold load resistors were replaced by capacitors because they have no Johnson noise;
| |
| − | * ii)that the detectors are biased by applying a triangular voltage to the load capacitors
| |
| − | which produces a square current [Ibias ] in the capacitors, and a square voltage [T bias ] that compensates for the stray capacitance of the wiring (producing a nearly square bias current into the bolometer;
| |
| − | * iii)that a square offset com-pensation signal is subtracted to the bolometric signal to minimise the amplitude of the signal that has to be amplified and digitized;
| |
| − | * iv)that the electronic scheme is symmetrical and uses a differential amplification scheme to optimize the immunity to
| |
| − | electromagnetic interferences;
| |
| − | * v)and finally that every parameter of the REU can be set by commands, which
| |
| − | is made possible by using digital-to-analog and analog-to-digital converters extensively.
| |
| − | | |
| − | | |
| − | | |
| − | | |
| − | The readout electronics consist of 72 channels designed to perform low noise measurements of the impedance of 52 bolometers, two blind bolometers, 16 accurate low temperature thermometers, all in the 10 MΩ range, one resistor of 10 MΩ and one capacitor of 100 pF. The semiconductor bolometers and thermometers of Planck-HFI operate at cryogenic temperature around 100 mK on the focal plane, with impedance of about 10 MΩ when biased at the optimal current. The readout electronics on the contrary have to operate at “room” temperature (300 K). The distance between the two extremities of the readout chain is about 10 m and could represent a point of extreme susceptibility to electromagnetic interference. The readout electronic chain was split into three boxes. These are the JFET box, located on the 50 K stage of the satellite at 2.2 m from the focal plane, the pre-amplifier unit (PAU), located 1.8m further at 300 K, and the REU, located on the opposite side of the satellite, 5 m away. Each of the three boxes (JFET, PAU and
| |
| − | REU) consists of 12 belts of six channels. The first nine belts are dedicated to the bolometers, and the three last ones to the accurate thermometers, the resistor and the capacitor (see figure Organization of the HFI readout).

| |
| − | | |
| − | From HFI pre-flight paper
| |
| − | | |
| − | See figure [Principles of readout electronics]. The bolometer is biased by a square wave AC current obtained by the differentiation of a triangular voltage through a load capacitance, in a completely differential architecture. The presence of the stray capacitance due to losses of charge in the wiring requires a correction of the shape of the square bias current by a transient voltage. Thus the bias voltage generation is controlled by the two parameters I-bias and T-bias that express the amplitude of the triangular and transient voltage. The compensation voltage added to the bolometric signal to optimize the dynamic of the chain is controlled by the V-bal parameter.

| |
| − | | |
| − | | |
| − | The interaction of modulated readout electronics with semiconductor
| |
| − | bolometers is rather different from that of a classical
| |
| − | DC bias readout (Jones 1953). The differences were seen during
| |
| − | the calibration of the HFI, although the readout electronics
| |
| − | was designed to mimic the operation
| |
| − | of a DC biased bolometric system as far as possible. With the
| |
| − | AC readout the maximum of responsivity is lower and is obtained
| |
| − | for higher bias current in the bolometer with respect to the DC model.
| |
| − | This is caused by the stray capacitance in the
| |
| − | wiring which has negligible effects for a DC bias and a major
| |
| − | effect for an AC bias. In our case, a stray capacitance of 150 pF
| |
| − | induces increases of NEP ranging from 4% (857 GHz bolometers)
| |
| − | to 10% (100 GHz bolometers) and also affects the HFI time

| |
| − | | |
| − | Taken from pre-flight paper
| |
| − | | |
| − | Given the high impedance of the bolometers and the length of the connecting cables, it it is essential that the impedance of the signal is lowered as close as possible to the detectors. In our system this is accomplished by means of JFET source followers, located in boxes connected to the 50 K stage. There are two JFETs per channel, since the readout is fully differential, and they provide a current amplification of the signal while keeping the voltage amplification very close to unity.
| |
| − | | |
| − | Inside the box, the JFETs are mounted on a thermally insulated plate with an active temperature control to keep them at the optimal temperature of 110 K. With a dissipated power lower than 240 mW, mainly produced by the JFETs and the source resistors, we obtained a noise power spectral density of less than 3 nV Hz1/2 for the frequency range of interest. This increases the total noise ofall bolometer channels by less than 5%.

| − | | |
| − | Due to Planck's nearly constant scan rate, the time response is degenerate with the optical beam. However, because of the long time scale effects present in the time response, the time response is deconvolved from the data in the processing of the HFI data (see [[TOI processing|TOI processing]]).

| |
| − | | |
| − | The LFER4 model has are a total of 10 parameters(<math>A_1</math>,<math>A_2</math>,<math>A_3</math>,<math>A_4</math>,<math>\tau_1</math>,<math>\tau_2</math>,<math>\tau_3</math>,<math>\tau_4</math>,<math>S_{phase}</math>,<math>\tau_{stray}</math>) 9 of which are independent, for each bolometer. The free parameters of the LFER4 model are determined using in-flight data in the following ways:
| |
| − | | |
| − | * <math>S_{phase}</math> is fixed at the value of the REU setting.
| |
| − | * <math>\tau_{stray}</math> is measured during the QEC test during CPV.
| |
| − | * <math>A_1</math>, <math>\tau_1</math>, <math>A_2</math>, <math>\tau_2</math> are fit forcing the compactness of the scanning beam.
| |
| − | * <math>A_3</math>, <math>\tau_3</math>, <math>A_{4}</math> <math>\tau_4</math> are fit by forcing agreement of survey 2 and survey 1 maps.
| |
| − | * The overall normalization of the LFER4 model is forced to be 1.0 at the signal frequency of the dipole.
| |
| − | | |
| − | The details of determining the model parameters are given in (reference P03c paper) and the best-fit parameters listed here in table table:LFER4pars.
