Dear colleagues,
Pretrigger setting programs are in
$CLONE_PARMS/pretrigger.
Two no-window programs premon and preset are controlling EC,
CC, and TOF CAMAC discriminators both for level1 and
channel discrimination. The output is a ASCII file of the format:
_________________________________________________________________
# this file contains info on crate, slot, mask, threshold, width
# created by vhg on 6/13 10:5:57
# blank lines and lines starting with # are ignored
*TIME*
866210757 # this is the unix time
*CC* channel discriminator data
4 1 ffff 50 100
*EC* channel discriminator data
6 1 0 20 50
6 2 0 20 50

*TOF* level1 widths for time of flight counter
99 99 99 99 99 99

_________________________________________________________________
For including TOF vpi discriminator information is used
tsl script running in dpsh. ex. $CLONE_PARMS/pretrigger/prt_mon.
Configuration files are in $CLONE_PARMS/pretrigger/conf.
Problems:
--------
EC channel discriminators:
crate7, 1-5 slots -> no Q response !
crate7, 6-20 slots -> Q=1, but no reasonable data.
TOF channel discriminators:
crate0, crate1 -> for all slots Q=1, no reasonable data ( dec: -276984848)
CC channel threshold:
crate4, slot 1 -> impossible to set mask, always FFFF
CC level1 threshold ( DAC):
crate2, slot1 -> Q=1, no data.
Results are double checked with cnaf.
vpi board discr. control.
-----------------------
I modified the program from Marchand ( previously modified by Elliot).
Modified version is in $CLONE_PARMS/pretrigger/s/vpi_src
I separated setting and monitoring functions and created
functions for mask manipulation.
set_vpi_width (board,width)
set_vpi_thresh(board,thresh)
mon_vpi_width(board)
mon_vpi_thresh(board)
set_vpi_mask(board,mask)
mon_vpi_mask(board)
NEED TO BE LOADED AND CHECKED!
GUI
---
SUN version of the GUI is compiled but not yet checked.
The original HP version is available for EC and CC level1 thresholds
(on clas10 ~clasrun/tm).
Today I will add to HP_GUI TOF level1 discriminators.
Regards,
vhg
