Header: 4.7 MeV/u and C_09. PS back, but need to check how much beam actually there was before next issue
Ender: no beam at our sample; IHS cavity (part of normal conducting linac) tripped

Sat Nov 11 17:36:54 2017, ASM, more halflife stuff
|
| Fitting those half life data more reasonably... fitted the decay curve with y=a*exp(-b*t)+c to all the data points, comes up with t1/2=(85.8+/-2.6)s |

Thu Sep 28 03:38:18 2017, dk, heavy ion degrader foil - updated 8x
|
--original email text--
Using Claudia's code, I added a layer of Al foil before the heavy ion
silicon detector. The attached plots correspond to the heavy ion

|
Thu Oct 19 14:41:19 2017, daid, heavy ion degrader foil - full / new 8x
|
See entry https://elog.ph.ed.ac.uk/ISOLDE/28 for a full description, but editing the same elog is altering attachment numbers etc.
Here I've added 20 um foil as well as 5.3 MeV/u (~313 MeV) 59Cu beam.

1 bolt for chamber stand structure, for reference for new struts.
2 target ladders: spare 1/2 style ladder, ladder from inside chamber, including the bits to connect to actuator
