Temp fluctuations in the Clean room appear to be +/- 6 degrees F.  There are no fans in the room yet to circulate air and the thermostat has not be set to minimize temperature fluctuations.  The air temperature outside the building has fluctuated from 60 to -12 degrees F.

So far for the clean room construction floor and design plans are almost finalized and will be posted by next Thursday (03/25/2010) and are not up this week due to a software problem cause from an Operation System Upgrade.

These designs will be similar to what has been previously posted.

As for temperature control, the graphs can be found [http://wiki.iac.isu.edu/index.php/Clean_Room_Temp_Sensor here].  As can be seen, the temperature has been roughly constant with only slight perturbations until the last couple of days.  This increase in temperature is probably due to the increase of temperature here in Pocatello.
+
[[ PhysicsCleanRoomParticleCountLog | ISU - Clean Room Particle Count Log]]
  
−
While within the accepted deviations, work will be done to ensure less fluctuations in temperature by working with Facility Services to get better temperature detection in the room.  Also, when the room is actually constructed, the walls should help prevent heat loss or gain inside the cleanroom environment to a greater degree.

Construction of the ISU cleanroom is anticipated to start near the beginning of May 2010 and will employ 1 graduate student to supervise and help with the construction.  Several REU students that are coming to ISU, plus some upper division high school interns.  Construction will be under full swing from May 2010 with anticipated completion by August 2010.

1.) Wire tension apparatus
 
  
−
A new technique (pulse method) is being developed for measuring the wire tension.  The wire is pinged every second.  The wire resonance is measured by a scope. The  scope does a FFT of the response.  Short wires are at a fast frequency but weak.  This requires sampling over many pings as the signal dies off quickly.  LOng wires vibrate so slowly that it is hard to measures the frequency.  Perhaps sampling the long wires over 1 ping is a better improvement.  Chris quevas has measured this and is not finding too much difference between using 1 or several pings.  Measurements take about 1 minute or less per wire.  THe goal is to measure 10 wires per minute as was done using the old technique.  The new technique is Labview friendly but it hasn't been implemented.  Right now the FFT is output to a text file.

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

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
