>> Add on slide 14 that the window with beam pipe attachment was
>> hydrostatically tested at 30 psi.
>> After that full assembly, the tank with the window, pumped down and
>> vacuum
>> leak checked. No leaks detected.
>> You also may refer to the window design and test document. I already
>> posted it on the wiki.
>>
>> You say:
>> "Vacuum Window is ready for installation
>> (estimated time: 2 days)"
>> This is outdated.
>>
>> The window is already installed on the tank. The tank with window will
>> go
>> to the Hall as one piece. Tank support cart is also assembled. So, we
>> will
>> crane the cart, and then crane the tank. Two lifts. The attache to the
>> target and to the downstream beam pipe.
>>
>> GEM photo on slide 9 is very poor quality. Can you find something
>> better?
>> You can say that GEM chambers are already mounted on the frame and this
>> assembly will go to the Hall as one piece to be mounted on HyCal.
>>
>> In addition to slides Make the Run Plan as a separate document, copy

>>> Some comments on the Run Plan.
>>>
>>> We should keep HyCal on the transporter for the test run.
>>>
>>> 1. There is no "Beam block" position for the collimator. We should use
>>> FSD
>>> interlock with tagger magnet power supply.
>>>
>>> Drop 1(b,c,d,f) It is pointless because HyCal will not be in the beam.
>>>
>>> Cell alignment procedure 2(l,m,n) should be changed to utilize
>>> additional foils
>>> with quadrants.
>>>
>>> Add GEM trigger delay adjustment.
