I have created two data bases of AMDA, see Figure 1. The conversion of the original EGSE files to the AMDA readable files is shown in Table 1

To compare the FS repetition and EQM repetition: Figure 5 shows the Day One HKs taken with the real flight procedure with EQM and SolO simulator at MSSL on 23 Dec 2019.
Note: the duration of the Engineering mode at MSSL procedure was 23 min. The real duration of the Engineering mode is exactly 20 min.

I have performed actions as follows ( Time of EGSE is shifted against the time of MAC to 7 min back ):
  1. ON (05/03 15:40)
  2. Start Sequencer 15:41, OK
  3. Security configuration: 0x1A, 15:47, ОК
  4. MHV UP, 250V step, 16:03, OK
  5. Security configuration: 0x1F, then 0x07, 16:05, OK
  6. ON CEMs , 16:13, OK
  7. Start Static , N = 5000, , 16:13, OK
  8. CEM to 1000V step 200 V, 60s, 16:31, OK
  9. CEM HV nominal = 1850 V, OK
  10. Burst mode, 90,4,9,0, 44,3, K =4, N = 19, start 16:52, stop 17:00
  11. Standard Normal mode (N = 1) start 17:01 (05/03)
  12. The vacuum chamber accident at 9:07 06/03 (see below the accident description)
  13. The instrument was OFF at 10:23 06/03
‌
The HK profiles for the experiment (for whole two days) are shown in Figure 6. The total CEM count, CEMs HV, and the corresponding currents are shown in Figure 7. Figure 8 shows the steps 1 - 10 (and start of item 11) with the zoom of the passage from the static scheme to the burst mode. Figure 9 shows the count and the corresponding HKs during the accident. It seems that the PAS count and the beam monitor were counting the ion scattered from the main ion beam due to the collisions in the vacuum chamber because of the low vacuum.
