[3dem] high EMF

[Alok Mitra]

Dear colleagues:

  The EMF measurements for the microscope rooms where our old T12 and the new TF20 (with GIF) are to be housed revealed values beyond the acceptable level. One of the remedial solution suggested is to utilize an active field cancellation device, which samples the field strength in real time and generates an opposing field to cance (placed near the objective lens)l. Does anybody have experience as to how well such a device performs? I will appreciate your input

   regards

   Alok
