TD, NS | RAL108 +/-15V PSU test at EAR2, n_TOF Monday 14 August |
On the morning of Monday 14 August 2x RAL108 +/-15V PSUs were borrowed from the Edinburgh equipment in the ISOLDE hall to check whether the same transient
noise is observed at the +/-15V PSU outputs.
PSU #2 Farnell MX2
Setup - attachment 1
DSO ch#1 +15V AC/1M, ch#2 -15V AC/1M - y: 50mV/div x: 1us, 500ns, 250ns & 25us/div - attachments 2-5
PSU #1 Coutant HSC15-3.0
Setup - attachment 6
DSO ch#1 +15V AC/1M, ch#2 -15V AC/1M - y: 50mV/div x: 25us/div - attachment 7
Conclusion
Observe same amplitude and HF structure with all 3x RAL108 +/-15V PSUs |

TD | RAL108 +/-15V PSU test in ISOLDE hall |
This morning 2x RAL108 +/-15V PSUs were borrowed from the Edinburgh equipment in the ISOLDE hall to check whether the same transient noise is observed at the +/-15V PSU
outputs - this was confirmed. See https://elog.ph.ed.ac.uk/nToF/63
Following this test the same 2x RAL108 +/-15V PSUs were tested in the ISOLDE hall ( 19" rack adjacent to the HIE-ISOLDE GP scattering chamber ).
PSU #1 Coutant HSC15-3.0
Setup and PSU details - attachments 1-4
DSO ch#1 +15V AC/1M, ch#2 -15V AC/1M - y: 5mV/div x: 400ns, 4us & 40us/div - attachments 5-7
PSU #2 Farnell MX2
Setup and PSU details - attachments 8-10
DSO ch#1 +15V AC/1M, ch#2 -15V AC/1M - y: 5mV/div x: 400ns, 4us & 40us/div - attachments 11-13
Conclusion
The noise of the 2x RAL108 +/-15V PSUs differed somewhat ( frequency and structure of HF transients ) from each other in the ISOLDE test.
Compared to the EAR2, n_TOF test the amplitudes were c. 10x smaller and the HF transient frequency and structure differed.
This appears to confirm that the primary problem is the ac mains power in EAR2, n_TOF - input and/or output filtering is required. |

Sarah | SPD card changed |
14 bit card replaced for DEED 9-12, to prevent issue with pulser arriving before gamma flash. |

Annie | Signal Spreadsheet info |
Spreadhseet made for shifters to manually enter that they have checked each signal and that they can see gamma-flashes. It is saved as "26Al_EAR2_Signal_Checks.ods", it is located on the second monitor on the right of the control room, next to the monitor used to see the beam intensity (same monitor used to see signals).
It will stay open throughout the campeign. Shifters have been told to check signals more than just the once to record that they're okay, and there is a comments box for shifters to add any comments/issues that arises after they have recorde that they have checked the signals at least once. |
