SPLITTING THE TARGET CHAMBER

Here are a few notes on the correct procedure to split the target chamber.

1.  Let the system upto atmospheric pressure in the usual manner by letting

gaseous nitrogen through needle valve 4.

2.  Disconnect the target ladder motor drive cable from the top of the chamber
 and also disconnect the turbo pump underneath the chamber.  Remove the
 connections from the pirani and cold cathode gauges and also the two flexible
 hoses from the chamber.

3.  Using two large spanners (exact size unknown)  loosen the top bolt followed
 by the bolt diametrically opposite or in this case the bottom bolt.

4.  Repeat for the left and right bolts and then for alternate pairs of opposite
 bolts.

5.  Remove all bolts when all are fully loose.

6.  Slowly pull the chamber apart making sure it doesn`t hit the stop too hard.

7.  The chamber is now split and ready for processing.

8.  To reconnect the chamber together repeat this procedure in reverse but
 remember to reapply grease to the O-ring.
