Entry  Monday, January 25, 2016, 16:54, Isaac Earle, Maintenance, Target 1, Cooling, T1 MRO Work 
The following work was performed at the T1 cooling package and target between January 18-21, 2016:
- Cuno water filters removed (3), and new filters installed
- Target water solenoid, H.E. secondary side solenoid, and Collimator A solenoids removed and replaced with new 24V DC versions

 this Work was done on 09 Dec 2021.
Since Isaac Earle was leaving Triumf he was giving us (maico, chad, adam, and myself) a demonstration of how to remove targets, protect monitor,
and wire scanner. During the removal it was noticed that one of the pins for the wire scanner was bent and it would not be possible to reattach without

 Graham Waters has activated the appropriate target ladder position look-up tables for the T1-MK1 target which was installed in the beam line yesterday.

On May 31, the low active water in BL1A was turned off briefly and upon re-starting, the flow to the T1 heat exchanger was very close to the reported
warn limit (~6 gpm). 
 
Entry  Monday, March 27, 2017, 16:15, Isaac Earle, Repair, Target 1, Cooling, T1 Cooling System Target Water Return Hose Damaged IMG_8077.JPGIMG_8076.JPG
The 18' shielding block which lies west of the T1 cooling package was removed on Friday Mar 24 so that vacuum equipment could be craned into the 1A tunnel.
 During replacement, the flexible SS hose for T1 target return water got caught under the block and was ripped apart.  Workers in the area did
not realize this had occurred.  The cooling package tripped off when the hose ripped (likely due to low water flow or low supply pressure).  In
Entry  Friday, September 30, 2016, 16:59, Isaac Earle, Repair, Target 1, Cooling, T1 Cooling System Inlet Pressure Transducer Replaced 
 The T1 cooling system inlet pressure transducer (EPICS ID: B1A:T1CS:PGIN,  Omega part # PX315-100GI) began failing in August (exhibited gradual
decline in pressure with no corresponding change to flow rate or outlet pressure).  A new transducer was installed on Sept 30 2016 which fixed the
problem.  Cyclotron Fault Report #9238 was returned and the temporary bypass on the warning level was removed.
Entry  Tuesday, July 18, 2023, 09:14, Adam Newsome, Other, Target 1, Cooling, T1 Cooling Package: target flow (FGTGT) sensor noise issues 1.PNG2.PNG
Between 1:00 pm and 6:00 pm on July 17, 2023, the T1 target cooling water flow rate sensor exhibited some noise which resulted in it dropping below the
warning/trip limit. The control room requested that the threshold values be lowered - permission was granted. The thresholds were set to 2.3 gpm for both
warn and trip levels. See attached screenshot from EPICS sensor data. The occasional spikes and dips continued throughout the night fairly consistently.

Entry  Thursday, February 02, 2023, 15:14, Albert Kong, Maintenance, Target 1, Cooling, T1 Cooling Package: Leaked Valve Inspection CompiledPictures.pdf
A 0.75" SwageLok ball valve that was taken out from the T1 cooling package was inspected (SS-45S12).
All valves in the T1/T2 cooling packages likely leaked due to damage to plastic/rubber sealing components. 
 
Entry  Thursday, April 03, 2014, 16:35, Isaac Earle, Standard Operation, Target 1, Cooling, T1 Cooling Package Started 
 The T1 cooling package was started around 2pm today.  There was no change to the T1 volume vacuum during startup.
The package was inspected for water leaks: None found.
The demin loop flow (Q2) was adjusted to ~1.5gpm.

 The T1 cooling package inlet pressure (P1) has been dropping since approximately May 5, 2013 from the regular operating pressure of approximately
75psi to the present value of 47psi.  An increase in the rate of decrease started around August 5th as well as increased noise in the signal.  Plots
attached below.  No corresponding change in the outlet pressure, and no change in the water flow rate (also no change in inlet and oulet temperatures)
Entry  Thursday, February 02, 2023, 10:35, Albert Kong, Maintenance, Target 1, Cooling, T1 Cooling Package Draining (Prep for Valve Replacement) 
Water reservoir in T1 started draining at ~7.30 am, will leave till tomorrow or overnight to fully drain. 
(Preparation to replace all leaky valves). 
Drained water samples collected for RPG. 
Entry  Tuesday, January 27, 2015, 17:38, Isaac Earle, Repair, Target 1, Cooling, T1 Cooling Package 3/4" Valves Rebuilt - T1 MRO Complete 
- Both 3/4" ball valves on the T1 cooling package target water circuit were rebuilt, leak tested with house air pressure, and reinstalled
- The 3/4" ball valve on the T1 heat exchanger secondary side was replaced with a new unit
- The 3/4" needle valve on the T1 heat exchanger secondary side was rebuilt, leak tested with house air pressure, and reinstalled
Entry  Tuesday, March 20, 2012, 10:31, Isaac Earle, Repair, Target 1, Cooling, T1 Cooling Package - Potential Water Leak 
The T1 expansion tank warning level sensor had tripped and the level was approximately 1cm from the base of the tank.  No trip warning was observed
when Tom Lyth checked the panels last week.  The T1 cooling package and target monolith were inspected and no water was observed.  Two puddles
of water were found in the BL1A tunnel around the T1 package area: one directly below the 1AQ9 Cable Interlock Tray, and another approximately 1.5m to
Entry  Friday, April 12, 2013, 17:33, Isaac Earle, Development, Target 1, Cooling, T1 & T2 high-temp limit switch installation, wiring, and commissioning complete 
Installation, wiring, and commissioning of the high temperature limit switches for the T1 and T2 cooling packages was completed today as part of SAS
project SASP0120.  The relay output from the switches was wired in series with the Central Safety System signals for T1 and T2 (cable number 13250
and 12250 respectively) in break-out panel #2 on the Meson Hall south mezzanine.  There were already 3 other circuits wired in series with each signal
Entry  Wednesday, February 05, 2020, 14:53, Isaac Earle, Maintenance, Target 1, Cooling, T1 & T2 cooling package MRO work completed 
 Annual MRO work on the T1 and T2 cooling packages is now complete.  The following tasks were performed:

    Water from both packages drained to the South TNF holding tank (samples taken)
    All Proteus paddle wheels, shafts, and
o-rings replaced (5 each at T1 and T2)
    All Cuno filters changed
    Archived data for all sensor readbacks inspected.  Only
Entry  Tuesday, May 12, 2015, 21:20, Grant Minor, Standard Operation, Target 1, Target, T1 & T2 Targets moved from pos. 0 to pos. 4 
Grant moved the T1 and T2 targets from position 0 to position 4 this evening at around 9pm.
The position 4 selector button on the T1 rack was not working.  The manual control box had to be used with the adapter cable and military
connectors for both T1 and T2 to achieve position 4 on both targets.
Entry  Tuesday, June 26, 2012, 09:05, Isaac Earle, Maintenance, Target 1, Cooling, T1 & T2 Target Water Flow Transducers Serviced T1_&_T2_water_flow.jpg
 The target water outlet flow transducers on the T1 and T2 cooling packages were serviced (new shaft, paddle wheel, & o-ring) to address a noisy
signal.  The service corrected the noisy signal.  Additionally, it appears the worn parts were causing the transducers to read high, as both
dropped approximately 1 gallon/minute after the service.  Both transducers would occasionally trip the high flow warning (8.5gpm), and should now
