Production
- Dave (see the Construction Tracking link above): cell#2 is ready, including one end window. Anatoly cleaned the wire frame manually. Second end window will be ready tomorrow. Will start very soon stacking the package, but need some parts. Cell#3: position measurements on the wire frame (Caleb and Al made a code that does it automatically, but has not been tested yet), making flaps on one of the cathodes and gluing rigid-flexes on the other one. Cell#4: wire frame is ready for stringing, one of the cathodes is being tensioned and the foil for the second is in preparation.
- We discussed if we can relax the clean room humidity requirements to save on the energy bill. The main concerns are the gluing operations and the Rohacell material being susceptible to elevated humidity. Tim explained: there's no humidity control and therefore it depends on the heat in the room (that's why it was elevated over the last weekend); we could increase the setting temperature from 69 to 70deg F to see the effect. Eugene: first we have to establish the production and then to investigate the effect of the humidity, even 50% is very high. Conclusion: at least for this month we don't want to change the settings.
- Bert Manzlak is trying to help us establishing a Radiation Control Area at Blue Crab and organized discussions with Keith Welch. RadCon are reluctant and are looking into the administrative papers if that is possible at all. According to Bert, a RCA was made off-site long time ago.
