PACS Cryo Harness 1

PACS IIDR 01/02 Mar 2001

PACSCryo Harness

U.Grözinger, D.Lemke, R. Hofferbert

Max-Planck-Institut für Astronomie Heidelberg

Based on input data from CSL, CEA, IMEC, KT, MPE

PACS Cryo Harness 2


Requirements

• Provide signal integrity for 14 useful bits of science data for 800 Ge:Ga-detectors and 2560 Bolometer pixels

• Provide stable and low noise supplies for detector bias, readout circuits, high resolution position sensors

• Independent supply groups for detectors to minimize risk

• Low resistance for actuator drive lines to minimizeheat dissipation and allow accurate controlling

• Low heat conduction

• Goal: Use of ISO-type cables as far as possible

PACS Cryo Harness 3


• Triaxial cables for Ge-detector output

signals

to reduce heat load at 4K-level

• Shielded twisted pair cables for BOL-

detector

output signals

• Low resistance cables for high current

lines
