Template letter:

To HKL Research, Inc.

The members of my research group lead by ...................... will be traveling to collect synchrotron data at the .... beam line at the European Synchrotron Radiation Facility on ..........., 2021. The beam line does not have the HKL license. As an academic, non-profit organization, we currently have a permanent, academic HKL license for our lab. We would like to obtain a temporary license extension to use the HKL software, while at the ESRF, so we can begin processing our data on site. While we are using the beam line that is involved in the industrial activities, the data we collect and process will be for "non-commercial use" as defined on your web site. It will be used for research that is not subject to any written agreement allowing a commercial or for-profit entity to impose intellectual rights restrictions on the published results or delay the availability of data and results derived with the use of the HKL software. The HKL software will be used exclusively by me and/or members of my group and only for projects that I control as a Principal Investigator.

Commercial HKL licensees need to have the HKL-2000 maintenance contract in order to obtain the license extension. It is sufficient to send us an e-mail request a few days before the experiment begins.
