I think the ion gun does better than the older method at removing the small dust particles; but it is pretty far from perfect, and many small particles remain bound to the the glass. The Ion gun is much better thank the copmressor by itself at removing/blowing off dust from metal srufaces. ___end___ GENERAL COMMENT BY berkey: Fri Jul 13 18:26:46 GMT 2018 Windows up stairs opened at 17:00 ___end___ GENERAL COMMENT BY berkey: Fri Jul 13 23:13:42 GMT 2018 F18 playing war over the saddle today ___end___ GONG COMMENT BY berkey: Sat Jul 14 01:15:54 GMT 2018 Power cycled the gong anneometer per a request from gong hq. ___end___ Sat Jul 14 01:16:31 GMT 2018 Kcor Focus/alignment program exited GENERAL COMMENT BY berkey: Sat Jul 14 01:47:29 GMT 2018 We will need to clean up the ion gun configuration over time. Right now both the power strip on the ladder and compressor are off and will both need to be turned on to blow off the o1. If we get the the point that we want to revert to the older O1 cleaning system; the hose is down stairs in the control room. ___end___ ONSITE STAFF: berkey
