X-ray delivery

• 7.8keV, 2.5mj, stable delivery, homogeneos intra train energy most of the time.

Optical laser delivery

• ns laser for particle imaging

Achievements/Observations

• RGA installed and used for quantitative gas BG analysis
• Data (55 nm Ag cube) and gas BG (no sample) measured with two different gases (N2 and He)
• BG roughly 3.5x better with 3 l/min He flow, but only about 2x better with 3 L/min He + N2/CO2 for stable Tayler cone

Issues

• Pulses often changed from 352 to 28 for no apparent reason, discovered later that it was happening when closing silicon 500 XTD2 arm (elog:421)
