  1. Gun conditioning is going very well and it was conditioned to 330keV yesterday. The scope is being brought up to 300keV in operation mode at this moment. The scope will be checked out after the beam is turned on and hopefully it will be available to users soon. We will keep you posted on the progress.

  2. All the tests on electronics were done and now The gun is being conditioned. The conditioning continues till noon and then the scope will be baked over the weekend. The gun will be then further conditioned to 300keV by the early next week.

  3. A new gun was assembled in the lab and now being tested. The old gun will be removed and the new gun will be installed sometime tonight.

  4. A new CFEG got delivered to our lab today. The gun will be installed tomorrow. We hope that Grand ARM will be up sometime soon. Stay tuned!

  5. JEOL determined that the cold field emission gun is dead. We need a new gun. It will take a few weeks to get another gun and then a few weeks to bring it up. Sorry for the inconvenience.
