Users are able to purchase the rulers (Toledo 150MSE) and mount samples prior to arriving at the beamline. This can also be done at the beamline (in the case of non-hazardous samples) or in the Synchrotron’s Chemistry lab. Carbon tape and fluorescent paper are available at the beamline.
MEX2 Sample Holders
To visualise the beam, the first approximately 7 mm of the ruler will remain blank for attaching a phosphor paper that glows when exposed to X-rays (shown in this picture).

Transmission measurements: the mounting ruler has windows (Photo A) allowing various transmissible samples to be mounted (Photo B). Transmission measurements and sample preparation is difficult at the MEX2 energy ranges. If the transmission is your only option, please contact the MEX beamline scientists before submitting your EA to discuss its feasibility, as the transmission is almost impractical to perform at MEX2. Choosing the wrong acquisition mode could result in your EA being rejected.
Sample preparation kit
MEX2 uses a ruler mounting system that allows stacking up to 16 samples vertically, as shown in the image below. Additionally, we offer small brass coupons that enable stacking up to 30 samples on one side of the ruler.
We have designed a sample mount kit specifically for MEX2 users, as shown in the picture below.
If you would like to receive the kit before starting your beamtime, please contact the beamline scientists well in advance, and they will assist you with the process.
Contact the beamline scientists well ahead of time.
