You can test this by changing the focus manually back and forth. You'll find that the image is still moving around even when it doesn't when you turn on focus wobble. The best way to align the aperture is to 'focus wobble' manually. This fact is noted in the GG lab version of the raith instructions which is on the swiki. Having said that, the 120 micron aperture has had the same problem since two bakeouts ago. As far as I know, the machine will just have to be opened up again and things realigned. HOpe this helps. Cheers, Charis.

Remember that the scan speed during gun alignment can affect the adjustment. For proper gun alignment, you should operate at scan speed 9 when in emission mode. I presume you knew this, but it is good that we have this email list just so we can double-check each other.

Problem: several nested interface problems to be resolved... Message-ID: <4075ECA8.5040605@snf.stanford.edu> Greetings, During a user session this morning problems were encountered with the IEEE-488 interface and other communications busses between the RAITH computer and the RAITH hardware. (IEEE-488 read errors) Specifically there was a problem with the interface that controls the X-Y stage and the switching of the Laser to the optical coders used to sense the Z height of the stage. Initially this resulted in a Load Lock error (5) i.e.. typically a hard hardware failure of the worse kind. I was able to clear that error and get the system to load and then ran into problems with the encoders... I spent the entire afternoon troubleshooting and have cleared up several nested problems that resulted from a loss of stage control and then again a subsequent loss of the IEE-488 interface. After reestablishing IEEE communications, I have been unable to reestablish control between the laser and coders on the system, preventing load/unload functionality as well as re-calibration of the stage. explicitly (FIND HOME POSITIONS) This also prevents unloading the system. Raith has been SMS'd and we will pick this up again in the morning. I am sorry I cannot get the system back up for this evening, and for the delay in your EBL work. System in red light mode and shut down until further notice.

Message-ID: <40770578.9070009@snf.stanford.edu> Hello: Despite best efforts from RAITH USA and myself the RAITH 150 will be off-line and in shut down mode through Tuesday afternoon. We have identified a bad GPIB board that is interfering with proper communications to the Precision stage controller and it is causing errors and loss of functionality to the stage motor control and virtual motor control modules in the software. I spent this morning working through these interfaces and testing the IEE-488 buses and communications and as of yet have not been able to figure a way to establish a work around to this sub-system.

Message-ID: <40774314.8000901@snf.stanford.edu> GREETINGS: Just placed the system into Yellow light mode....for the weekend. The schedule is open! Please be careful and observe the load and unload sequence. I made adjustments to the GPIB polling time and repeat status to GPIB device (0) i.e., stage X and Y and possibly laser to coder switching section Now seems OK after 3 test of load and unload. Test writes appeared OK as well. If IEE-488 error encountered use this workaround: Open Module status panel Highlight ICE Motor control: Press reset module... Highlight Virtual Motor control: Press reset module ... Press OK, and continue with your unload by pressing retry or continue, NEVER CANCEL... I also completed adjustments to the gun alignment and aperture settings and saved to the standard files for the system. You can accept these values for ~5.001 mm when prompted and you should be good to go. The only aperture out of specification is the 7.5 um aperture which exhibits decided shift when the focus is adjusted despite the gun and aperture being adjusted. Near the maximum range for this aperture. LEO will come in next week to realign this and check out the system again -- TBD. Whew what a week. Happy Easter!

The threshold for the arcing events we observed before was in the 26.5 keV total acceleration voltage range. Keep in mind that the beam booster section of the column accelerated electrons from the 8 keV primary energy to the specified kEV through the 20 kEV range. At 20001 - 20100 Volts this section shuts off and ramps back to 0 and then without the beam booster section applied accelerates electrons to the specified higher acceleration voltage. So 20 kEV results in 28 kEV potential between the gun tip and the anode plate. I have requested LEO to return to assist in evaluating this problem, but with no response thus far. I escalate this with LEO in Germany in the morning Friday their time. Mike Santomango with LEO has been MIA since I returned from Germany two weeks ago, and I am continuing attempts to reach him, or someone with suitable knowledge here in the USA.

(Of course this was just before I was to press the Scan ALL button...) This appeared as an actual EHT trip in the FE-Gun as I observed a slight spike in EHT current as it shut itself down. Gun Vacuum remained in the 1.5E-009 mbar range and did not exhibit elevated levels of vacuum. After a half hour at idle with EHT off, I ramped back up to 18500 Volts and was able to resume my work and performed some test writes with no further EHT trips. The threshold of the EHT trips, and / or arcing appears to be about 26.5 keV, the same as the level we observed just after we brought the system back up. Users are requested to carefully evaluate if they need higher acceleration voltages for their work. Users are requested to operate the system in the range of 0.3 and 18000 volts of acceleration voltage and 20100 to 21000 keV. Please do not exceed these levels. If you experience a EHT trip: - Please note the voltage it tripped at in the logbook and report as a comment in CORAL. - STOP and do not attempt to return to that voltage level that caused the trip, and after a 15 minute rest period to let the system pump, return to less than 18000 volts and resume you work if possible. - If the gun will not come back up after this wait period please call me directly my cell. Thank you, James Conway Note: BEAMER, the Hitachi HL-700 always is running at 30 keV. It may also be useful for your work albeit with normal cautions and challenges that this system may present. jwc at snf.stanford.edu wrote yesterday: Please stay below 18 keV until further notice: -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: <4091269D.8070601@snf.stanford.edu> Greetings Raith Community: Several users have reported that their Photonic Crystal circles written with RAITH circle function have been elliptical or not completely cleared out on positive PMMA resist. I am working with several users on this and may have identified two trends that could result in this phenomenon. 1. Beam speeds are allowed to be too high!! Be sure to inspect your exposure window and ensure that the area write and line write beam speeds are below 10 mm / second. This is to ensure you do not experience fly back effects as the data arrives to the deflection system before the beam reached it proper position. This is likely a result of using old parameters and aperture selections with the new improved Beam current we achieved after the recent PM. Features written in the X direction will become elongated, circles become ovals. 2. Area steps are too big!! Note that the area step parameter is employed to place the RAITH single pixel line (SPL) in the pattern written in RAITH circle mode. This will result in shots that do not connect or overlap during your EBL write. Features written will have very rough line edge roughness and have an appearance of swiss cheese or closed area of your circles. Other users observing this or other strange write results are requested to report to this list and include measurements and images if possible. You may stop by during my office hour as well.
