−
To monitor the ISU clean room's temperature and humidity, an array of temperature probes will be used, with one probe being a temperature and humidity probe.
+
[http://wwwold.jlab.org/Hall-B/clas12-web/  CLAS12 Web page]
  
−
The probes used will be Sensatronics's Standard Temperature Probe.   These probes will cost $60.50 and we will be purchasing five of them.  The spec sheet can be found at:

One of the probes will be the Sensatronics's Temperature/Humidity Combo Probe which ISU already has. The spec sheet can be found at:

To convert to from analog to digital the Sensatronics Model EM1 Environmental Monitor will need to be purchased. This device will hook up through Ethernet and allow for up to 12 probes to be hooked up to it. This will allow for continual monitoring of the clean room once it is in operation. This device will cost $438.90.  The spec sheet can be found at:

−
The total cost will be approximately $760.00 to get the temperature monitoring up and running in the room for the ISU clean room.  Once the temperature probes are up and everything is configured, we will have a real time monitoring of the temperature with web access and logs to see how the temperature fluctuates over time.  These graphs will look like the ones used for the BREMS cluster temperature monitoring graphs.  These plots can be seen at:

===Construction Proceedures:===
 +
 
 +
Chambers outside cleanroom should have covers to keep dust off buss wires
 +
 
 +
Cap 113 (Brown one) needs to be replaced on STB board.
 +
 
 +
 
 +
Need 2 amp fuse on 5 Volt supply to pre-amps.
 +
 
 +
operate chamber STB voltage at 6 Volts
 +
 
 +
 
 +
 
 +
Chamber grounding (ground through HV cable)
 +
 
 +
===Chamber operating procedures===
 +
 
 +
1.) post amplifier in VME crate had 150 mV peak-peak noise
 +
 
 +
2.) Stop using the current ADB crate
 +
 
 +
3.) New nominal Voltages from Mac are
 +
 
 +
S:F:G = 1300:-650:
 +
 
 +
S/F = 2
 +
 
 +
S/G = 5/7
 +
 
 +
Signal output doubles every 75 Volts difference between sense and field
 +
 
 +
 
 +
 
 +
4.) Discriminator level for signals:
 +
 
 +
5.) Need to lower the HV trip current back to 1 microA.  May increase it to 5 micro Amps when burning in.
 +
 
 +
6.) Change trip speed to 0.1 sec
 +
 
 +
 
 +
 
 +
 
 +
===ISU Tasks:===
 +
 
 +
1.) Install cover on top of chamber,  top could be made from home insulation sheets that has been covered with paper or plastic sheeting.
 +
 
 +
 
 +
2.) Install 208 Volts for ADB crates that will be sent by JLab to replace the one they have given us.
 +
 
 +
3.) solder jumpers onto HV boards, install them in January when George returns
 +
 
 +
4.) Mylar window on S1 chamber needs to have some tape and weather stripping redone or modified
 +
 
 +
5.) Get allen head 3/32 for torque wrench, remember to replace brass screws if they are removed for some reason
 +
 
 +
6.) do not do final instrumentation, purge covers, and dust covers on the last 2 chambers until checking with JLab, the may want to survey them after delivery
 +
 
 +
 
 +
 
 +
===JLab Tasks===
 +
 
 +
1.) What are the fault conditions on the STB board when the power supply exceeds voltage/current
 +
 
 +
2.) Need signal cables with strain relief connects that have the shielding wrap grounded on the STB board but not grounded on the DAQ cabinet
 +
 
 +
 
 +
3.) George will send purge covers and come back in January to install

Cap 113 (Brown one) needs to be replaced on STB board.


Need 2 amp fuse on 5 Volt supply to pre-amps.

operate chamber STB voltage at 6 Volts


Chamber grounding (ground through HV cable)

Chamber operating procedures

1.) post amplifier in VME crate had 150 mV peak-peak noise

2.) Stop using the current ADB crate

3.) New nominal Voltages from Mac are

S:F:G = 1300:-650:

S/F = 2

S/G = 5/7

Signal output doubles every 75 Volts difference between sense and field


4.) Discriminator level for signals:

5.) Need to lower the HV trip current back to 1 microA. May increase it to 5 micro Amps when burning in.

6.) Change trip speed to 0.1 sec



ISU Tasks:

1.) Install cover on top of chamber, top could be made from home insulation sheets that has been covered with paper or plastic sheeting.


2.) Install 208 Volts for ADB crates that will be sent by JLab to replace the one they have given us.

3.) solder jumpers onto HV boards, install them in January when George returns

4.) Mylar window on S1 chamber needs to have some tape and weather stripping redone or modified

5.) Get allen head 3/32 for torque wrench, remember to replace brass screws if they are removed for some reason

6.) do not do final instrumentation, purge covers, and dust covers on the last 2 chambers until checking with JLab, the may want to survey them after delivery


JLab Tasks

1.) What are the fault conditions on the STB board when the power supply exceeds voltage/current

2.) Need signal cables with strain relief connects that have the shielding wrap grounded on the STB board but not grounded on the DAQ cabinet


3.) George will send purge covers and come back in January to install
