Helium pressure test on all water lines: 70psi , 3 minutes. HS has a quick response to 9Xe-9atm.cc/sec for 20 seconds. No response on other lines. All water lines are good. Air to vacuum  leack check on ITE and TM4: TM4 IG1 / Steers side panel has a low E-6 atm.cc/sec leak. The o-ring need to be changed when TM4 is located at TCS. All other air to vacuum seals are good on both primary and secondary vacuum vessel.

 TM#2 has been moved from the conditioning station to the south hot cell.

Preparation on TM2 move from TCS to SHC.

  On February 8th the SMP shield box (IRH1675) and the vacuum vessel (IRH1806) were both raised from a horizontal to vertical orientation in the ISAC-1 Experimental Hall.  Hamilton "Mini-Mite" S-MM2-43FS caster wheels were then installed on the base of the shield box and it was lowered down the hatch to the B2 level.  The vacuum vessel was then lowered into the shield box, supported by the rollers, as designed.  The shield box and vessel combination were then moved south along the steel plated floor until positioned under the hatch leading to the Target Hall.  Movement along the floor was achieved by pushing the back of the vessel with an electric fork truck and pulling from the front with a cable winch attached to a plate mounted in the floor in the SHC service area, centered east/west between the Ante Room doors.  The fork truck alone was sufficient to move the assembly on the smooth section of the plates, but the winch was needed on the section paitned with textured grit.  The vacuum vessel was then lifted into the Target Hall and placed in a temporary storage location in the silo area.  The shield box was then lifted, casters removed, and then lifted up into the Target Hall.  It was a very tight fit with the tubing which has been installed on the SHC and NHC ducting for the new flow meters, but the move was completed without causing damage.  The shield box was placed on the B2 level in the Target Hall where some final tapped holes will be added on the exterior before moving to the final installation location.

 Franco Mammarella was consulted regarding electrical grounding of the NHC design (RS103 of Document-131915).  After discussing the design, and having grounding inspected by Randy Boehm, Franco approved the design and advised that the grounding system should be inspected periodically.  This task has been added to the Remote Handling inspection index on an annual schedule.  A PDF copy of the e-mail correspondence with Franco is attached.

leak detector base LR: 0.0Xe-9atm.cc/sec. helium 70 psi. test time : 3 minutes for each circuit.The results in atm.cc/sec are Ta+(A):1.8  XE-8. TA-(B):0.0xE-9. Tu-(C):1.2XE-7. TU+(D):1.6XE-7. Coil 2 (PQ):0.0XE-9. Coil 1 (RU):0.0XE-9. MSP:2.2XE-7. EE:1.0XE-7. HS:N/A. Window:5.8XE-9

3 damaged 24VDC plugs of TP solenoid valves are replaced. Inspected other plugs. All of them are in good condition now.

ITW water system maintenance is done. All working paddle wheels and coils are replaced. ITW water system polyurethane tubes are replaced as well. Two 3/8" leak small valves on return lines are replaced. 85 liters of tritium water are transferred from storage tank to B2 level holding tank. LALC water are refilled into S-tank. Restarted pump and checked system. Everything works fine now. No water leak has been found so far.  

 The NHC right side monitor has been wired to display the signal from the in-cell camera.  This was tested using a snake camera on both of the CPC-4 connectors.

The following NHC development work was completed under WP I2019-01-09-4:

• Location of RH feature on operator level LED lighting updated to match IRH1800 Rev B design
• Remote Handling test of the LED fixtures was repeated using a 9' pole with hook attachment through the manipulator slave hatch from the Target Hall: both LED fixtures were removed and reinstalled successfully with relative ease
• Tool port seal replaced to address an audible air leak: the 1/4" foam seal was removed and replaced with adhesive backed 5/8" wide hollow foam rubber seal (McMaster Carr PN: 93085K81). Prior to the change DPG4 was at 0.63"wc, after the change wit was 0.73"wc with all system variables constant.
• NHC manipulator access block seal was replaced, likewise to address an audible air leak: the 1/4" foam seal was removed and replaced with adhesive backed 1/2" thick BunA-N rubber strip (McMaster Carr PN: 9023K85).  DPG4 was at 0.94"wc prior to the change, and 1.07"wc after with all system variables constant

No issue.

SMP drivetrain design work is currently underway.  Alejandro has selected a suitable 1200:1 reducer which will give a vessel rotation speed of 0.21rpm with a 1725rpm motor (deemed sufficiently close to the SHC rotation speed of 0.17rpm).  The reducer however is only rated for 0.33hp, and Allon's analysis recommended we use a motor of at least 0.4hp

I will restart all pumps Monday morning.  

 The spent target in the south hot cell has been moved to the spent target vault. It was placed in pail 204 and placed in spot 6B. The pail is made of thicker steel and thus will not need to be repackaged later.  The ISAC spent target vault is full there is no more room for any more targets.

TCS: TP1, TP2 and TP1S are started.

 TM#2 has been moved from the south hot cell to the conditioning station.

ITH: MP1 has been replaced due to its poor performance.  Its motor and power cable are taken out and reused on new pump. Vacuum group assembled them together, and installed the new pump. The new pump works fine.

 Electrical check of the target module with the UC#25 attached after the beam run.

 TM#4 with UC#25 has been moved from ITW to the south hot cell.

The tCS will be vented soon for TM2 move later this week.
