|
The new box has been tested together with the new CAEN SY4527 power supply. We connected a laptop with Linux to the power supply by means of an ethernet cable and communicated with it by opening a browser (http://192.168.0.1, then username: admin and pwd: admin). To control the channels we open a terminal, go to the folder where we saved the file ChannelsController.jar and run the command: java -jar ChannelsController.jar 192.168.0.1 admin admin
The output biases were checked with a test cable connected to the flange output and are reported in the attached file. For comparison we did the same thing on 3 Mugast detectors (MG1, MG3 and MG4) We saw that the polarity of all the 3.3V in the new box was inverted with respect to the Mugast box so we opened the box and, like sappers, we followed the colored cables until we found the ones giving the 3.3V and inverted them. It worked! So now the biases should be correct. A reminder for possible future modifications: the coupled colours for the wires are blue-grey, white-brown, yellow-green.
Some low voltages seem to be unused because they are present in some BT outputs but not in others, but anyway the detectors which are supplied by these cables have always been working properly, so the small differences between different BT outputs might be irrelevant.
It is then important to notice that BT2 and BT3 have a -2.5V instead of a +2.5V so it's recommended not to use them unless the relative cables are first switched inside the box. |

|
After a quick offline check, it seems that we get MUGAST data only if MUGAST has triggered (GATCONFMASTER = 1,2,4).
In the de/TOF spectra the different structure in time are thus not due to different timing between VAMOS and MG triggers. |
