08:16 - as run 18, target off
9:00 Increased storage time to 5 minutes. Aquired data after initial beam loss. Attach 1 &2. Far less H2+ vs D.
Temps OK
Rates as before
10:00 beam being optimised to reduce 2H+ content
Rates in aida 13, 14 suddenly spike as during overnight. Checkloaded repeatedly. No effect. Increased thresholds in 13, 14 to 0x32 bringing them in line with 15,16.
