Here is an exemple of the file to put on the web.

I wanted to put the datas sent by Guillaume and Stefano on our directory 
on afs
in the directory called /afs/cern.ch/eng/lhc/blm/md, but I do not have 
the write rights in this directory. I can  transfer the files only in my 
subdirectory Laurette.
If it is OK, then I can add in the txt file the location of the logged 
files (BLM data, jaws movements, BLM ring datas)

********* Collimators BLM acquisition software

login on blr51s as user opera 
cd  /user/biswop/bin/LYNX603_4.0.0/blring_sps

then run the software with the users-options:
blmCoast <-debug> <-acqDelay 1->100> <-intGain1 0->255> <-intGain2 0->255> <-ampGain 0->7>

    Where the bit-mask intGain1 (and intGain2 for totem) determines
whether for each channel the integrator gain is low = *1 or high = *200 ..

bit 0 corresponds to high gain 200, bit 1 corresponds to low gain 1, 
 
(ex: intGain1 = 15 sets BLM 1,2,3,4 to integrator gain 1 and BLM 5,6,7,8 
to integrator gain 200.)

    The amplifier gain handling is common to all channels on the two
cards.


typedef struct myBlm {
         struct timeval timing;   /* long seconds, long useconds local
time on BLM CPU   */
         int      acqNumber;      /* acquisition number since program
restart            */

         int      ampGain;        /* The common gain for all 16 channels
(2 cards)       */
         int      intGain1;       /* The integrator gain entered for
card 1              */
         int      intGain2;       /* The integrator gain entered for
card 2              */

         short    blmData[16];    /* the values integrated for this
acquisition          */

         int      scTime;         /* The time when the acquisition was
started    */
         int      scNumber;       /* The super-cycle number for this
acquisition  */

} blm_struct;

!!!!!!!! It's worth mentioning that only ONE 'blmCoast' process can run at any
time on 'blr51s' and that you have to stop an already running one to change
the gains or acquisition delay ..

THe datas are logged by Guillaume Robert-Demolaize software.

********* SPS ring BLM

cd /user/biswop/bin/hpux/blring_sps

to run the software

> blgetacq blrba5 cycle_code 0

with cycle_code 0301 for LHC beam

To store the datas, ask the operator to run the software and 
the datas are saved in:


/user/slops/data/SPS_MD/COLL_11102004/COAST*/BLRING for the MD on 11/10/2004
/user/slops/data/SPS_MD/COLL_18102004/COAST*/BLRING for the MD on 18/10/2004
