Proposal for a stantard H.V. controls log book

C. Diarra M.M. Aléonard Edition 1.0 November 1990

Object: make a repertory of the characteritics of high voltage for each detector − log book to be built progressively from the tests of the equipement −. The results from this log book will be analysed to set the experiments controls.

Voltage and current values used for the EUROGAM detectors with the Lecroy HV 1400 series power supply: set of parameters to be used for setup and control of experiment

RESULTS OF TEST

(a) detector identification from higher level user interface

(b) detector id, example:

• GUOC17 serial number for Ge

• BGO id and PM id for BGO

We need one such sheet for each Ge detector and its BGO shield.

Please give us any comment on further information eventually some feed back on evolution of current versus count rate for BGO and current critical value for Ge (warming up).
