I will be running some experiments this weekend that will
require more nitrogen than what is presently in the cylinder.
Could a fresh cylinder be installed this afternoon?
Thanks, DB

A new N2 cylinder has been installed.

>>> 'dcl' problem from jchung -- Wed Jun 28 14:18:11 1989 <<<

Although the N2 tank for the cold chuck is not completely empty,
could a new tank be installed?  I plan to use the chuck 
extensively over the long weekend.  Th  The tank is almost empty anyway.

Thanks,

Jim Chung

>>> 'dcl' problem from evan -- Fri Jun 30 15:22:16 1989 <<<

a new n2 cylinder (#1969ST) has been installed. The pressure is 2400 psi.
I received the wrong CGA fitting for the high pressure (3500psi) cylinder.
The correct fitting should arrive in time for the next cylinder change.  This
should provide a much longer interval between cylinder changes in the future.

>>> 'dcl' problem from jchung -- Mon Jul  3 09:49:45 1989 <<<

I used up the n2 tank for the cold chuck over the weekend.
Could a new tank be installed before the holiday tomorrow?

Thanks,

Jim Chung

>>> 'dcl' problem from bob -- Mon Jul  3 14:00:13 1989 <<<

Problem: N2 cylinder at 1700psi.
Solution: Replaced cylinder with a used cylinder (2200psi) as there
          are no HP N2 cylinders available with the correct CGA fittings.
          removed=19695T, TOO6 @ 1700psi
          reinstalled=AH10085, TOO6 @ 2200psi

>>> 'dcl' problem from jchung -- Tue Jul  4 12:04:41 1989 <<<

Over the 4th, I burned up what was left of the N2 tank
that was installed.  When convenient, please change
the n2 tank.

Thanks.

>>> 'dcl' problem from evan -- Wed Jul  5 10:22:20 1989 <<<

Replaced the CGA fitting on the regulator with a CGA 680.  This allows
connection with 3500 psi N2 cylinders.  Installed new cylinder #HP543.

>>> 'dcl' problem from jchen -- Wed Jul 12 16:03:38 1989 <<<

Could someone change the gas tank in 407 Cory for cold chuck. Thanks.
The pressure is running low.

>>> 'dcl' problem from evan -- Thu Jul 13 08:52:06 1989 <<<

A new 3500 psi cylinder #HP10068 has been installed.

If heavy use of the cold chuck is expected (for a week-end, month or all
summer), please let me (evan@argon) know so I can plan how many cylinders
to keep in stock.  Thanks for your help.

>>> 'dcl' problem from evan -- Fri Oct  6 11:07:02 1989 <<<

The high pressure, 3500 psi, cylinder has been reconnected.  
The ccold probe can now be used again.

>>> 'dcl' problem from burnett -- Fri Nov  3 16:29:32 1989 <<<

On Monday I will run an experiment that should exhaust the
current N2 supply.  If possible, could a new N2 tube
be installed on Monday, preferably in the am? 
Thanks, David

A full N2 cylinder, #HP859, has been installed.

Bob:

Are you the correct person to ask to have
some air lines install into the new
characterization lab (your old office) ?
They are needed to generate vacuum for
both the automatic probe station and EMMI.
EMMI also needs the air to move the chuck.

Thanks,

Yupin  yupin@argon

There appears to be a steam leak in the HVAC of the dcl 
(Rm 407). I will report this to Eleta. The odor in this 
room is likely caused by the anti scaling compounds used 
in the steam system. It should not be a health problem.

>>> 'dcl' problem from bob -- Tue Jan 16 10:56:27 1990 <<<

Jim Chung has providied a list of priorities of service
for the dcl. These are:

1. Reinstallation of the cold probe (evan)

2. Installation of an air line and rehookup of
   the electroglass (phill)

3. Installation of water and a drain to the hot chuck
   to be done only when ok'd by Jim Chung as the
   tool is under high useage.

These jobs have been prioritized and assigned.

>>> 'dcl' problem from evan -- Wed Jan 17 09:18:01 1990 <<<

The high pressure cylinder of n2 has been reinstalled on the cold probe in
the new location.

>>> 'dcl' problem from phillip -- Wed Feb  7 14:24:18 1990 <<<

Update: The air supply and return lines in rm.409 are almost
complete. The hot chuck H2o installation is also close to
fruition. Both of these should be up by tomorrow noon.

The work that was initially requested by Jim Chung is
substantially completed.
 The hot chuck, although plumbed, has yet to be turned on.
CAn Bill Flounders or Jim call me when this is activated?

Jim, please stop by and see me when your schedule permits.

An order has been placed through McBain Inst. (1-818-998-2702)

one will be installed in the defective illuminator when it arrives.

Replacement sockets for the B&L illuminatos have been ordered.
They will take 6 weeks to get here. All illuminators in the dcl
will be checked and repaired when these parts arrive.

Room 407 is exceedingly hot and uncomfortable. A report will be
amde to eleta to have the Stationary Engineer check this room out
and service as needed.

This report will be cc'd to eleta for action.
