EDM wires

It's been a while.

Any copper wires can be used for EDM.  I learned that wire diameter can be decreased by 10-20% by stretching it.  So 120 micron wire can ben stretched to drill 100 micron hole.

Happy DACing.

FWHM in CONUSS

Total number of points which can be assigned for the width of EFG in CONUSS is limited. If too many points are assigned for the width, CONUSS crashes but does not specify what is wrong.

Ar loading

In order to prevent blow out, Ar loading should be done before or at least at noon. We don't know why. But we found there is much less chance of blow out in morning loadings. This is particularly true in Summer time when humidity is high.

Make Ubuntu+CONUSS faster

Make sure you have the following commands in Ubuntu.bat file.

-----Ubuntu.bat--------------
REM Start qemu on windows.
@ECHO OFF

net start kqemu

qemu -L . -kernel-kqemu -localtime -soundhw all -hda hda.img -m 512

Do not load Ar without humidity control

Cryogenic Ar loading should be done at humidity below 40%. Otherwise, sample chamber would expand during or after the loading
