This afternoon, Travis and I finished the necessary part removal to drop the Lower structure and it's 6 masses from the ITMx suspension in BSC3. Mark D helped us run the arm and the elevator controls to bring the unit out. We had one small hiccup where we accidentally yanked a wire off the reaction chain top mass which was snagged on UIM hardware. We'll have reinspect the this top mass and then hit the lab to rebuild the wire segment. Win one for poor lighting, not have an infinite supply of eyeballs and snaggletooth UIM structure hardware sticking up during this procedure. Thanks in advance for Jeff K's pictures likely coming to the alog.
In other news:
Jeff B and I were able to successfully* swap the SRM surrogate mass for the full SRM optic SRM-06. I first contacted the HR surface prior to installing it. We measured weights prior to install:
SRM-06 2885g (2886g with the FC sheet)
Surrogate 2905g
Jeff added 20g to the middle mass in order to compensate for the loss of weight to the SRM optic stage. Jeff and Hugh are currently working on setting pitch and roll.
*Successfully: the optic was not damaged, the wires of the suspension were not broken, the optical lever we were attempting to use was only mostly compromised. While trying to sight the far side wires around the prisms during the install, I rolled a shoulder into the temp oplev beam staged on the table - even though it was placed as far out of the way as possible. Darn cramped spaces! Oh well, the pitch info from it is still useful and we have other ways to course align P/Y. Final alignment will happen early NOV with PSL beam.
IO has continued efforts in HAM2/3, still at it now...
Hugh finish install of needed feedthrus on HAM5.
In words, I've:
- Created coil driver monitors in h1susauxh2 and h1susauxh56 for all new suspensions, re-arranging as mentioned above
- Updated the FOUROSEM_MONITOR_MASTER to use full filter banks instead of just test points and EPICs Monitors
- Changed the stored channel name list to include the "VOLTMON_??_OUT" needed for filter banks as opposed to the test point which was just named "VOLTMON_??""
- Only IMs, RMs, and OMs, use this library part so there's no need to recompile other susaux models
- Changed the PR3 optical lever ADC channel assignment in the h1susim model on the h1sush2b computer and removed the HAM2 table optical lever (these were picked up by h1sush2b sent out over the dolphin PCIE network to h1sush2a for consumption in the h1suspr3 model)
- Removed the OMs for the h1sushtts model (but the RMs remained), and changed the h1sushtts model to run on the second user model core (specific_cpu=3) of h1sush2b computer
- Changed the ASC control IPC receiver channels from shared memory (SHMEM) to over the dolphin PCIE network (PCIE)
- Terminated all of the OM inputs to the HTTS ODC vector
- Installed the OMs into the h1susomc model of h1sush56 computer
- Brought in an ADC1 block for the OMs
- Changed all the ASC control IPC receiver channels from SHMEM to PCIE
- Did NOT create any new ODC vector, so terminated all the status output from each HSSS_MASTER block
- Modified the h1asc model IPC outputs for the RMs and OMs to use PCIE instead of SHMEM
- Found that IM4 TRANS (sent by h1ascimc on h1asc0) was never received by the h1asc model (on h1asc0), so we hooked up the receiver... but are still suspicious how initial alignment ever worked without this...
- Created a new model h1susopo
- Installed ZMs using HSSS_MASTER.mdl
- Created new library parts VOPO_MASTER.mdl and OFIS_MASTER.mdl, and installed those as control in top-level model
I attach a bunch of screenshots of tghe finalized models to guide the eye -- and to guide the install at LLO.
The following models have been compiled, installed and are running:
- h1susauxh2
- h1susim
- h1sushtts
The following have been compiled, but we'll wait until next Two Tuesday to install them (due to work on replacing the SRM, and our need for more electronics)
- h1susomc
- h1susopo
- h1susaush56
Next up -- MEDM screens, and especially, re-populating the RM's control systems.
