Hi, All,

The Smartlab is down due to the Servo/encoder error. The service is called.

The Rigaku engineer came on June 2 and repaired the Smartlab.

Thanks,

Hi, All,

The UltimaIII is up running.

The XG tube was replaced. The previous tube reached its lifetime.

The optical alignment and maintenance was done. The UltimaIII is up running!

 

Thanks,

Hi, All,

The UltimaIII was down due to an XG-related error on April 16. I am troubleshooting on this issue.

Will update the status once it is up running.

Hi, All,

 

The Evaporator was down in the weekend of Aug 31 due to the CTI 8200 compressor failure. We tried to purchase a new CTI compressor, but the lead time is 8 weeks that is too long. We contacted several compressor vendors asking for the quotes for a new compressor and/or refurbished one. Finally we decided to purchase a M125 compressor from Trillium. The order was placed on today, 9/11.

We found that the cryopump has an issue with He decontamination and needs to be replaced. The order for a new pump is placed on Oct. 1 and will arrive in a few days.

The new compressor will arrive on Oct. 2.

Users could expect that the Evaporator will be up running in the earlier next week, 7th of Oct.

The new compressor and cryopump were installed. The system was regenerated successfully. The Evaporator was up running on Oct. 11th, Friday.

 

Feel free to let me know if you have questions.

 

Thanks,

Hi, Magellan users,

The Magellan is down now. The source beam is not stable. FEI engineers will continue to troubleshoot this issue tomorrow.
Please reschedule your experiment for tonight and tomorrow sessions. It is likely the source need to be replaced. We will find out  with proper tools tomorrow.
Sorry about the inconvenience. I will keep you updated on the status.

Thanks,

Hi, Dear Magellan users,

Some immersion modes are having problems with imaging. It is likely there are particles get into the deep part of pole piece. The FEI engineer is scheduled to work on this issue on Sept. 11/12. The Magellan will be down on these two days.

 

Thanks,

Hi, XL30 users,

 

The XL30 is down now due to the vac and chiller issue.

FEI service was called for the vac disabled issue on Jan 19. We  removed the moisture in the gas lines and replaced the tubing between compressor and instrument.  On Jan 20, we found that the chiller temperature control had an issue. The cooling water was over cooled and water drops were condensed on the cooling lines. We trouble-shot and ordered the thermostat part for replacement. It will arrive next Monday or Tuesday. I will keep you updated.

On Jan 24, the new thermostat was delivered and installed into the chiller. The chiller was cleaned and re-filled with fresh distilled water. The XL30 is up running now.

 

Thanks,

Hi, XL30 users,

XL30 is down due to ODP failure. The new part will come in tomorrow and FEI service was scheduled for repair tomorrow.

The ODP temperature sensor and heating sensor were ordered for replacement.

The XL30 is up working on Dec. 9, 1pm.

 

Thanks,

Hi, All Xl30 users,

 

The XL30 is down due to the chiller failure on Oct 14.

The part was ordered and delivered on Oct. 25

The chiller is back up running on Oct. 19

The SCSI (electronic printed board) error message and ODP oil level low message showed up during the system recovery.

The FEI service engineer is ordering new parts and will come back to work on the XL30 recovery.

 

The XL30 issue was solved and back up running on Oct. 21th

 

Thanks,

Hi, All Magellan Users,

On Oct. 10, a service call was made to deal with users report about imaging shifting. The service engineer came in and found that the e-beam source filament was not conditioned well (under heat) and current was too small (92uA). The more heating current was input to extract more current.  We would wait for more current and more stable.

Oct. 12, the e-beam current 180uA was observed. The source alignment was performed till 4:30pm.  Another service was planned on this Friday Oct 14.

Thanks,

Qiyin
