> > 01.02.2021 - Four new sets of PSU, HDMI & Ethernet cables were ran from the DESPEC rack to the AIDA frame, in preparation for 4 new FEE64s. > > A new 7 port USB hub has also been placed for the last few serial connections. > > > > For the first experiment this year, we will run with a narrow AIDA configuration as in 2020. (12 FEEs) > > > > The system has been powered up and biased successfully. To be monitored over the next few days. > > > > A lot of the FEE serial monitors are missing, I think a hub has been disconnected from nnrpi1. This will be investigated on Wednesday. > > The rack will also be grounded properly on Wednesday to investigate the impact on the noise. > > > > A single new water line (feed and return) needs to be installed for the 16th FEE, this will be done once the hose is found/ordered... > > > > The 4 new FEE64s will be mounted and powered up at some point to obtain the MAC addresses, and possibly check MIDAS merging 16 FEE64s. > > > > Waveform data will be taken wednesday before & after grounding the rack to see noise situation currently > > 05.02.2021 - > The serial hub was disconnected and was reconnected. Unfortunately nnrpi1 seems to have gone offline so cannot be used still. Will try to reboot pi when possible. > > The hose has arrived and the water line will be prepared in my office mid next week. > > All the leaf MACBs have been updated to the latest firmware (MACB_GSI_Simple.jed) and set to mode '0'. A fourth leaf MACB is now in the NIM crate but has no HDMI connections in or out yet. > All 12 FEEs powered up and have no WR issues (one MABC was first set to wrong mode, but was fixed) > > A new tape server to support unmerged waveform readout has been loaded and documented by VP. This will largely be unused but the option is there and will be tested. > > The rack was grounded to the platform floor with a large cable to potentially improve situation. Waveforms before (fig 1-2) and after (fig 3-4) attached. > > There will be a DESPEC Dry Run next week Mon-Tue. Encoding: HTML ELCode plain Suppress Email notification
