LEP Collimators



The following views for each of the experiments and the aperture collimators have been created on the LEP Measurement Database.

NOTE: Don't forget to prefix the view name with 'lepmeas.' to be able to see it.

V_AP_COL
V_L3_COL
V_ALEPH_COL
V_OPAL_COL
V_DELPHI_COL

Example : The following call returns the collimator names & positions of interest to L3.

select to_char(timestamp,'DD-MON-YY HH24:MI:SS'), hw_name, position
from LEPMEAS.V_L3_COL;


Here you find PRO*C and C code which demonstrate the use :

Example PRO*C Program to access the collimators of interest to L3

Example C Program which calls the above routine

A trigger will update the collimator table in the Measurement Database as soon as a change to the control database occured (change in collimator position).
