Penning + Pirani 3 Gauge: 2 x. Penning + Pirani Between skimmers 1 -2 Gauge: Penning 2 V 3 goal: use flat skimmer instead of pyramidshape Gauge: Piezoelectric (? ) Hi-pressure nozzle primary from CERN Hao: experimental skim 3 Ne V 3 goal: most probably primary only 1 4 5 DN 63 63/100 adpt. DN 63 TMP 300 l/s 63/100 adpt. TMP Gauge: Penning + Pirani 300 l/s Primary • Leak det. valve • 2 venting valves Primary • Leak det. valve • 2 venting valves V 3 goal: DN 63 opening, DN 63 ->100 adaptor and 300 l/s pumps Primary • Leak det. valve • 2 venting valves

Goal: • Imitate version 3 schematics with experimental setup • Get “matrix of pressures” at every step • Change 1 parameter at a time • Pressures as a function of injection pressure (0 -10 bar) • Each data point with e-gun off/on

DN 100 gasket with 63 hole I don’t think DN 160 gasket with 63 mm hole needed since there is 3 skimmer upstream DN 160 gasket with 32 mm hole Hi. PACE 700 here with standard gasket before CERN Elbow arrived Hi. PACE 700 with 63 mm hole gasket here before CERN Primary pump arrived DN 160 to DN 100 adaptor + DN 100 gasket with 63 hole + Hipace 300 Slide: Hao Zhang
