| Issue | Description | Date Added | Added by | Actions Taken | Status |
|---|---|---|---|---|---|
| FEB chiller | Disconnected after found dirty | 5/6/2019 | tkn | Replaced, new chiller plumbed in and running. Serial control is up but needs testing. | unresolved |
| Wiener LV card | Card won't power - slot 4. On initial look, slots 4+ in crate had no power | 5/8/2019 | tkn | Swapped in spare card located in slot 10. See logbook entry | resolved (OM) |
| FEBs | Not all working | 5/8/2019 | tkn | Swapped L6B -> L4B (perfect) and put partially repaired FEB3 (three bad adc channels) in L6B. Can consider further replacement if perfect spares are achieved. (TKN) | unresolved |
| Alignment | Alignment of L1-3 relative to wires is unknown | 5/19/2019 | tkn | Survey/adjustment was performed by JLab alignment group to set box in same position as before relative to beamline. Motor positions were determined to set horizontal wires at beam height to create a reference point in lever sweep and vertical positions of lever ends were recorded at those positions. Positions of silicon relative to wires are still unknown and may require further outputs from the detector model as well as L0-3 survey data. | unresolved |
| Cable Labels | Label cabels to SVT/FEB chillers | 5/8/2019 | mrsolt | unresolved | |
| Chiller Serial Cable | Redo spliced connections of the serial cable to SVT/FEB chiller | 5/8/2019 | mrsolt | unresolved | |
| SVT Chiller Webcam | Setup the SVT chiller webcam to monitor fluid levels | 5/8/2019 | mrsolt | unresolved | |
| Checked motor decoders | Need to understand if motor decoders need to be replaced | 5/9/2019 | omoreno | unresolved | |
| Check motor controller | Verify that motor moves the expected distance when moved from the GUI | 5/9/2019 | omoreno | unresolved | |
| Re-set motor home and operation position | New layer 0 modules requires resetting motor positions. | 5/9/2019 | omoreno | unresolved | |
| Add SVT variables to EPICS | Before, values were retrieved by parsing the XML. Now, rogue will provide us the variables directly. | 5/9/2019 | omoreno | unresolved | |
| Add RTD to SVT Chiller outlet | We have a broken RTD on the SVT chiller outlet, and we should replace it | 5/9/2019 | mrsolt | RTD removed and placed on table for survey. Need to have returned to SLAC. Need to order new RTD to get reworked. (TKN) | unresolved |
