hi savannahites,
in trying to get a handle on the needs of precursors on the system, i've
scheduled some regular changes over the next month.  as usual if you need
something urgently, let me know, but this should accommodate most needs as i
see them.

ammonia, water, TDMA-Hf, and trimethylaluminum will always be on the system.
 the other two lines will have 3 different precursors rotating through.

March 30th:  Yttrium and diethylzinc on; TDMA-Ti off
April 6th:       TDMA-Ti and Yttrium on; diethylzinc off
April 13th:     Diethylzinc and TDMA-Ti on:  Ytrrium off
April 20th:     Yttrium and diethylzinc on; TDMA-Ti off
April 27th:     TDMA-Ti and Yttrium on; diethylzinc off
May 4th:       Diethylzinc and TDMA-Ti on:  Ytrrium off

we'll plan may more as april closes out.  if you know long term plans,
please let me know.
