Hi,
There seem to be a lot of problems with the cables to the scintillators.
Could I suggest that you not handle the cables so much. At the moment
whenever you use the START or PADDLE detectors you steal cables from the
TOF and re-route them to the new detectors and then put them back (but
typically not as neatly as they were originally laid). Also this means
using and modifying the HV daemon for the voltage settings of the new
detectors and putting it back for the TOF values. All of this leads to
mistakes and damage.
The patch panels on the sub-detector have spare SHV and BNC cables to the D
tunnel. There are spare HV cables which can be used from the patch panel
to the new detectors and I am sure you can get spare BNC cables made.
Similarly there are spare HV pods so the new detectors can use their "own"
HV channels. In this way you can have the START and PADDLE detectors
without taking apart a hopefully working TOF detector.
Also I notice that now a lot of cables and fibres are hanging down onto the
sub-detector rails, etc. Opening and closing the sub-detector now requires
that you watch these cables and move them to avoid damage.
This is just my opinion.
Cheers,
Douglas
