Yesterday the TBHT was ramped to 250 amp and the TGHT was ramped to 440 amps. Attached is the data from that run the strip tool that had this screen
shot crashed but it can be recreated with the data. The TBHT ps was not reading back accurate results as such there are large steps in current or voltage
or some instability for no apparent reason. In addition to this the ramping program is still not working so the ramping was a very manual process. The |

|
Yesterday TM3 had the TGHT current raised to 160 amps and the TBHT raised to 200 amps. At this power the TGHT showed typical results in that vacuum
was affected and the increased voltage as the target increased in temperature. The tube heater on the other hand did not change voltage or show a change
in vacuum. As a result it is believe there is a short somewhere in the module. I have attached a screen shot of the strip tool and the raw data. |

The high voltage was sparking several times during the night. It may be correlated with the cycling of the cooling water temperature and conductance.

Monday, April 08, 2024, 09:29, David Wang, Cooling, Standard Operation, , , HALCW system general inspection.
|
water are supplied to both ITE and ITW. I did a general inspection on HALCW system. Two small leaks on 2" shut off valves are fixed. No other leak
has been found so far. all water flow meters work fine. MP2 pump discharging pressure is ok which is just above 100 psi on local gauge reading. pump noise
are low. pump body temperature is less than 45C which is good. |

|
HALCW system O2 sensor service and calibration were done in Sep 26th. electrolyte and membrane on rose mount sensor 499ADO were refilled and replaced.
Sensor was zero and full scale calibrated. The sensor works fine after the job. |

|
HALCW resin tank has been replaced. The old tank is stored in middle-west silo now. The field on old resin tank bottom is about 3.5 msv/ hr(on contact).
By shielding it into silo and putting two lead blankets on the top cover of the silo,The general field 1 feet above this silo is 25usv/hr. And, The field
around the silo area are less affected. This old tank will stay there as long as possible. For the new resin tank during preparation, It was found |

|
Two of resin tank filter cartridges(supply and return) are changed today. Old cartridges and bagged and tagged. The contact field on them are 650usv/hr.
The new cartridges are fiber-glass, Triumf store item. After replacement, the field on contact with the filter case are about 10 usv/hr. But the field
on contact with top resin tank has been increased from 45usv/hr to 225 usv/hr |

HALCW resin can flow meter replacement is done. Less that 100 mL water was drained to a small tray during the job. RPG checked the water. Less than 20
counts. Water are dumped the high active sump. The HALCW MP1 is started. No leak on new gauges and fittings. Old gauge is labeled , bagged,
and stored in TH. |

HALCW flow sensors replacement job is done. All ITE/ITW(except ITE HS) return line water flow sensors including paddle wheels and coils are replaced.
After job, water interlock signal have been checked in electrical room . Everything works fine. Visually inspections for possible water leak on HCLCW
system have been done as well. one valve on ITE dump return line has a very small water seeping through valve stem. I will watch on it. Other than |
