RIKEN tubes on the AIDA side with the SHV right angle connector will protrude
by ~95mm in the HYBRID configuration (with CLOVERS).
In the current AIDA DSSD configuration there are six detectors occupying 45-50mm

You can start applying HVs on the detectors using macro on the control-computer.
If you have already signed in the computer that controls mpod,
1. Type http://192.168.13.239/ to monitor the status of HV. |

Today several tests (3) were done with the germanium detectors with the voltage configuration listed in the previous entry.
The tests were as follows:
Tests with 60Co+137Cs sources |

Expected Resolution:
------------------------------
G7 should be ~2.0 keV FWHM at 600 keV for all crystals. |
