Week of March 1, 1999

HAPPENINGS:

MST VENT
The MST vent for hole drilling has been postponed.  MST wants to install
and take data with an antenna array prior to the vent.  In addition,
machine conditions are good and many people are requesting additional run
days.  Other than ourselves, there are few here who seem to be
anticipating the vent, and as a result, it hasn't even been brought up
during the weekly meetings.  I approached Prager yesterday and asked for a
general time frame; his best guess is beginning of May.  There are many
things that can occupy our time between now and then (primary subassembly,
deck construction, HV installation, a wedding, primary support
fabrication...), so I am not overly
perturbed by the delay.  Our image in DOEs eyes is yet more of a concern.
I would propose, given the significant duration of the delay, that we
occupy our time wisely and move forward with design and fab of the
secondary beam line.
Oh...okay...I suppose John might like one or two days (or weeks) off to
recouperate first.  (Of course, we should first finish up all primary beam
line items.)
PRIMARY BEAM LINE TRANSITION CHAMBER
The MST machine shop has finished work on the primary beam line transition
chamber (it really does look like R2D2). Both sections of the chamber
still need to be leak checked. Steve Oliva will leak check the assembly,
but has requested that we seal all surfaces. Mark Thomas would like for
the nose section to be sealed with the o-ring surface against a plate with
a machined port and surface simulating the MST o-ring sealing surface.
All other surfaces should be sealed with their respective
gaskets. Those here would prefer that we do not use rubber stoppers or
clay and plates. I will get all of the necessary parts.
HIGH VOLTAGE SHELF AND HV ENCLOSURE
The unistrut for the HV enclosure has arrived. Uday and Lei will precut
the unistrut for future assembly.
Bill Zimmerman and I will begin working on the HV shelf, precutting and
welding, as early as next week.
TRAJECTORY CALCULATIONS FOR THE LEVITATED DIPOLE EXPERIMANT (LDX)
Lei has updated the field model using suggestions and derivations supplied
by Ken and Tom. This model more accurately approximates the near field
regions.
HIBP13
HIBP13 is now up and running. It's now known as rentech2 (Rensselaer
Polytechnic ..., I didn't get a vote!).
HIBP PRESENTATION
My HIBP presentation on 17 Feb. was well received. Lei, was up to bat
yesterday, giving a presentation on sweep plate design, operation... It
too went well. Per Kens suggestion, we will try to get both of these and
future presentations onto a web page.
LAB SPACE
Some lab space has been offered for our use over in Sterling Hall. I've
looked at the space; presently it is filled with furniture and lab
equipment which others are supposed to come and claim. There is a
plethora of other Junk (including many chemicals) as well; Dale will
arrange and help with cleaning it out. There is a
high likelihood that the space will only be available for our use through
mid summer. I have made it known that this arrangement is less than
optimal, but that if it is our only option, we will take the space and use
it for subassembly, testing and storage. The biggest downside to the
arrangement that I see is not the distance; we can get there by the
freight elevator and ramp connecting the two buildings, but the
inconvenience and time loss of possibly moving our equipment twice, and
isolation from MST group including supplies and support staff.

CRATES FROM RPI
We've received the crates, shipped from RPI. I have not opened them nor
unpacked them since there are no remaining, unoccupied vertical surfaces
in my office. I will unpack them and send the crates back once some of
our new lab space is cleaned out.
