Light ions in the source 20mSpeaker: Detlef Kuchler (CERN)
Dear Marek,

I contacted some colleagues who have a lot more experience with different elements than me
(as you know I run most of the time lead).
- Magnesium seems to be very easy
- Aluminium needs a quite high oven temperature, so I do not know, if our oven can run like this and for how long, this would need some extensive tests
- to produce Silicon one cannot use the metal directly, but there is a gaseous compound - Silane, unfortunately this is highly explosive
- with Phosphorus both of my colleagues do not have any experience
- for the production of Sulphur ion beams one uses generally the Sulphur oxides, which are corrosive, this is not a problem for short runs, but as we are running months this becomes a problem
So, looking at this list, Magnesium really seems to be the best candidate. Second best could be Aluminium.
Best regards
Detlef
