1 A Bolometer Array Instrument for Millimeter Wavelength Philippe Camus, CNRS-CRTBT (Grenoble) Milano, July 6th, 2001

2 Bolometric Millimeter Camera Sunyaev-Zel’dovich effect High-Z objects and star formation regions imaging at 1mm => wavelength 1.2mm /2.1mm Which detector at 2.1mm? IRAM 30m Field 5X5 arcmin

3 Today and future Instruments MAMBO (IRAM 30m) 37 bolometer array on Si3N4 membrane (MPfir)

4 Optical Layout Cryostat Dilution mK Adaptation to ‘any’ detector Arrays

5 NbSi Bolometer (CSNSM/ Service d’Aéronomie) Bolometer on thin Si 3 N 4 Memebrane 5X5mm e=100nm Thin film geometry optimisation (typ. 100X400  e=100nm) NEP = W/Hz or W/Hz

6 Small Array Development (6X6 detectors) NbSi layer co-evaporation & Lithography Objective 8X8 bolometers

7 Electronic Read-Out Multiplexing is required to reduce the number of output amplifiers (JFET) Low dissipation/low temperature operation (HEMTor MOSFET?) Objective of 8 detector/amplifier
