MA02 horizontal field magnet
Above 150 K, the liquid He consumption get very high. For a short time 300 K is possible, but not recommended.
Dark Angles
Vertical opening
Vertically, the access to the sample is a 30 mm split with 282 mm diameter. This means for example a 10 mm sample can be fully illuminated with a horizontal beam when tilting +- 4 deg.

Pending Issues
The LHe consumption is higher than specified, but acceptable
(hold time ~ 2 days).
It seems, that care has to be taken during cooldown, as under
some circumstancies, the consumption gets very high (hold time
less than 1 day).
