This calendar shows availability for TREE kits to be booked throughout the year. Registration is open all year but there may be certain times that are better for collecting (winter does pose some challenges). Also, be aware that synchrotron data can only be collected when there is beam available and this will impact processing of samples. You will see maintenance periods or shutdowns indicating this time on the calendar. You are able to collect samples during this time; we will process samples sent to us as quickly as we are able to, but cannot guarantee a specific timeframe. Contact us if you have questions and/or keep an eye on this calendar or CLS operations schedule (looking for green, normal day shifts) for when data can be collected.
