[ccp4bb] weak magnet of goniometer of MAR345dtb

[aidong]

Hi,

We have recently installed a new home source diffraction system using  
MAR 345 dtb. It works much better than the rigaku because this new  
device has automatic motor control system.  However, we have a lot of  
trouble to mount crystals.  The magnet of MAR goniometer is  
significantly weak so the pins do not stick on.  The old pins we used  
nicely in old rigaku are not working most of time.  The new pins from  
hampton research particularly designed for ALS high-through put data  
collection are not easily working either.   I wonder whether anyone  
has similar experience and it could be fixed by replacing with a  
stronger magnet base.   Thanks for your suggestions in advance.

Sincerely,

Aidong
