The quadrant photodiode acquiring previously the B5_QD2 beam is now used to acquire the B1s_QD1 beam .

To be compliant with the new name of the beam, we  proceeded with the renaming of the B5_QD2 channels to B1s_QD1 channels .

The operations were performed between 2026-09-08-06h39m28-UTC and 2026-09-08-09h18m52-UTC 

Below the details of the operations performed:

• SDB2_dbox_bench server
  • DBox SN106 - demodulation mezzanine SN87
    • rename  as SDB2_DEMOD_B1s_QD1 instead of  SDB2_DEMOD_B5_QD2 previously
    • add the demodulation of the B1s_QD1 beam at  6MHz, 50MHz, 56MHz and 112MHz  for the 4 quadrant sectors
  • DBox SN007 - ADC2378 mezzanine SN43
    • renamed as  SDB2_ADC_B5_B1s_QD instead of SDB2_ADC_B5_QD previously
    • add the readout of the B1s_QD1_{H,V,SUM} channels  instead of the B5_QD2 ones
• SDB2_Tpro server and SDB2_ Fb server
  • Replace the old Tolm packets' name by the new ones
• SDB2_Quadrants  server 
  • Remove all the functionalities related to the B5_QD2 quadrants channels 
  • Add the last part of the demodulation of the B1s_QD1_{6,50,56,112}MHz channels
  • Add the B1s_QD1 galvo loops part
• SDB2_readout server
  • swap the B5_QD2 channels with the B1s_QD1 ones
• QPDMoni server
  • change the name associated to the interface ethmt7-2011 as B1s_QD1 instead of B5_QD2
• ASC_Acl server
  • the internal channels labelled B1s_QD1 are build using the SDB2_B1s_QD1 input channels
  • the internal channels labelled B1s_QD2 are build using the EDB_B1s_QD2 input channels
  • the B5_QD2 channels used in the TX_SENSING matrix and in the TY_SENSING matrix have been replaced by the B1s_QD1 respective channels
• Automation servers. ARMS_LOCK, DRMI_LOCK,
  • The related python config files have been updated by commenting the parts related to the SDB2_B5_QD2 quadrants 
• DetMoni server
  • all the parts related to the B5_QD2 quadrant photodiode have been commented
  • the monotoring part related to the B1s_QD1  quadrant photodiode have been added and remains to be tuned
  • A new flag B1s_QD1 has been in the DMS interface : the DMSserver server has been restarted to take in account this modification
