COUPP/PICO Operations Summary Main objective over next 6 months is to continue particulate sampling and understand particulate nucleation of bubbles – Water from both PICO-2L and COUPP60 extracted via filter in early July – Clear evidence for particulates in both, samples sent to PNNL for radioactivity and chemical analysis

COUPP/PICO Operations Summary Test chamber set up at Fermilab to do spike tests, now running at Lab A Testing radon emanation sources now Will do particulate spikes through Aug-Sept

Season 2 started on August 15, 2014! First few nights had excellent seeing (resolution), setting some records ~0.6 ‘’ Two large air conditioners installed and started running to control daytime temperatures. This will further improve seeing. Year 1 data processing is nearly complete. Y1A1 dataset will be released later this Fall. Shortly after that initial public data release will take place. Serendipitous discovery of superluminous supernova. One of several papers to be submitted this Fall from early DES data. Dark Energy Survey Seeing on Aug. 15 Supernova DES13S2cmm Before SNAfter SN Subtraction

Holometer (E-990) Operations Status: Stability is most impacted by low frequency external noise. Recent fixes: Tethered external hut to concrete blocks to reduce wind noise below 5 Hz transmitted into ground motions Tuned feedback loops to add resonant gain at problematic frequencies and reduce gain elsewhere to maintain phase margin Installed laser periscope enclosures designed to reduce turbulent flow of air driven by temperature gradients (and hence reduce refraction noise) 8/25/2014 Design beam intensity already achieved with sensitivity to m/rtHz disturbance amplitude Analysis is underway on 30 minute dataset for first graduate student thesis Focus now on improving operations stability to more easily gather 10’s of hours of data
