BaBar Drift Chamber
Environmental Sensors
Monitoring
(updated May 4th 1999)
For
any questions, or details contact : Vincent
Tisserand (Annecy IN2P3)
or
Hassan
Jawahery (University of Maryland).
For the Hardware part
at
Maryland
:
Rob
Bard or at SLAC
: Dave
Nelson or John
Dusatko.
For General questions related to DCH slow control
: Mauro
Morandin (INFN Padova).
For Others questions about the EPICS programming
of this application :
Fulvio
Galeazzi (INFN Padova) or Chris
Brown (University of Victoria).
and also Jim
Olsen
(University of Maryland) the second expert for the system !
The readout of the
sensors is done from ADCs scanning the sensors and read by micro-controllers
that are daisy-chained and transmission is done through a CANbus cable
and received on a VME Board of a VME 177 crate and monitored with the EPICS
software.
It is forseen to equip the different Quadrants of
the Rear Endplate of the DCH by micro-controllers with station number
27,
25, 28 and
29
(respectivly
for quadrants 0, 1, 2
and 3) and the
micro-controller for the Forward Endplate monitoring has station number
24.
2. Some
usefull links to other related pages :
3. Presentation
14 july 1998 (status and overview) actual current
status : software available for use and yes it's running (precise location
of sensors in the FEA boxes has sitll to be checked ...) and
also presentation
of 29 October 1998.
4. How
to have the software Running ? (some tricks and
ways to proceed for the common users)
very old documentation written for 1998 data taking
and Winter cosmics runs !!!!
5. Experience
from LAB August Cosmics Run
