Dear drytek1/2 users --

Drytek1, sadly, is no longer with us.  Within the next few days, its 
former location will be taken by a new Oxford III-V etcher.

Drytek2 users, please be prepared to share the machine with former 
drytek1 users.  This will be in effect starting in the morning on 
Wednesday, Sept. 28. Of the 6 electrodes, the top four will remain 
dedicated for clean/semiclean processing and the bottom two will be 
dedicated for gold-compatible processing.  Make sure to observe good lab 
practices and don't mix electrodes with incompatible materials.

Drytek1 users who are not already qualified on drytek2 will need a brief 
retraining.  Please contact Nancy for arrangements.

Drytek2 users:  yes, I'm afraid you lose two electrodes -- but the lab 
also gains the first of several new etchers.

Please check Coral or the Wiki for qual data to be posted soon.

Thanks for your patience -- and please do let us know your concerns.
