keyword=TECH - Left arm collimator problem
We were trying to move the left arm collimator from the 6msr position
to the sieve position but unfortunately, when it failed to move once we applied a high voltage, the collimator failed to move - either up
or down! All the gui controls appear to work and readback, but the
collimator does not move when the voltage is applied.
After discussion with the run coordinator, we called the tech-on-call,
Mark Stevens, who explained that we had done everything correctly and
it was going to take an access to check the collimator.
The run coordinator decided that we would proceed with our current
runplan as much as possible and then ask for a controlled access in
the morning (around 8am) so that the tech staff can check the collimator.
