Tuesday, May 14, 2013, 13:26, Isaac Earle, Development, Target 1, Target, T1 & T2 Profile Scan
|
The T1 and T2 profile monitors were used during today's development shift. Target ladder movement for T1 was done at the panel on the mezzanine,
for T2 the portable control box was used. Both monitors actuated properly and the scans did not show any "missing" wires. The profiles
at both targets were found to be too broad and were adjusted to span 2 wires horizontally and 6-7 wires vertically (Yi-Nong Rao). |

Wednesday, May 14, 2014, 20:36, Grant Minor, Development, Target 2, Target, Target exercised to position 0, then back to 2.0 mm above position 4
|
The T2 target was exercised to position 0 around 6:15pm so that the T2 profile monitor could be used by operations. The T2 water package was re-enabled
when the target was in position 0, however this resulted in some trips of the cooling package.
Operations called around 7:45 to request return of the target to about 2mm above position 4. |

Wednesday, April 22, 2015, 09:46, Isaac Earle, Development, Target 1, Target, Water Sensors Installed on T1 Monolith
|
Four water sensors have been installed on top of the T1 monolith. These water sensors were wired and brought to the area during the 2014
shutdown, but installation was delayed so that the top of the monolith could be painted first. The sensor labels (attached to the sensor cable) are:
T1, T2, T6, and T8. The location of each sensor is documented on the diagram below. Two photos of the top of the monolith are also attached. |
