The RASNIK system, a CAMAC based alignment monitoring
system, using a 4-quadrant diode as a sensor (4 channels per module).
The muon trigger interface for L3, containing: MPC, PAC, PCC-P,
PCC-Z, PCS AND PCT (FastBus modules). For L3Cosmics, the MPC is
replaced by the CPC.
The VRASNIK system, a VME based alignment monitoring system,
using a 4-quadrant diode as a sensor. Together with four VRASMUX
modules,
76 channels are handled. Used in L3, monitoring the relative positions
of the muon chambers.
The Helios is a highly sensitive smoke-detector, developed in
cooperation with Minimax AG.
The SRTD, PreSampler and BPC detectors in ZEUS use a remote
controlled
high voltage system to feed the photo multiplier tubes.
The
NIMROD is the interface between the MDT front end electronics and
the data acquisition system and second level trigger in Atlas. The
prototype has run for several years in L3Cosmics.
The
phase calibration of the Monitored Drift Tubes in ATLAS is a
proposal to find the phase relationships of the Front-End components on
the MDT FEBoards.
The
L3Cosmics project is an extension on the existing L3 set-up. NIKHEF
(Amsterdam and Nijmegen) is responsible for the read-out of the muon
chambers, inparallel of the existing muon trigger and read-out system.
It is also ademonstration project and test set-up for the NIMROD.
We have used JTAG in a large extend, in L3Cosmics and other
set-ups. Though there are various possibilities to drive such ports, I
found
it useful to be able to connect directly to a PC. I wrote a program in
BASIC (DOS) to do so. You can find the program and documentation over here .
