Results of the 2012 User Survey

These are the current results of the 2012 user survey. Latest update: Oct. 2nd 2013.


Be cautious!

The numbers are not straight forward to interpret, so please spend a minute reading through the page explaining the user counting procedure.

We were counting users which were active during the time 01/06/2010-31/05/2012. We used a 2 year time span to avoid effects from proposal submission deadlines; to reduce the influence of downtime for example from construction work; to also include users which come on a regular basis, but not every year. Some tests show, that a one year survey would come up with very similar numbers, so the 2 year timespan does not so much affect the total number of users but rather levels out exceptional events.

The definition of an active user slightly varies from facility to facility. In principle, we consider anyone (including facility staff) an active user who was during that time span

  • on a proposal submitted during that time, including rejected or currently reviewed proposals ... or
  • on a proposal submitted prior to 06/2010, but which entitles for beamtime during the time span ... or
  • on a beamtime application ... or
  • visiting the facility as a user

The definition of an active user does not have to be absolutely identical for each facility, in case a user management system can not exactly match the criteria. For example, some facilities might not distinguish between proposal and beamtime application. Some facilities don't record in-house users the same way as external users. So the numbers given below might well be very inaccurate in some cases, but we try of course to minimize potential errors. An entry saying, facility A has 2345 active users during the 2 year time span, just means: facility A had at least 2345 users, but might actually be much more.


Current status of the user survey:

The table shows the number of the hashes received and the number of unique entries. Duplicates have been filtered out, which results in the difference between number of users and hashes. Numbers in brackets are for the individual photon/neutron sources in cases where sites operate more than a single source.

Unique and Common Users

  • Note: numbers are still preliminary.
  • Remarkably, all facilities have users in common with all other facilities, also across neutron and photon sources. Typically, 30-40% of the users of any of the photon or any of the neutron sources also use at least one other facility. The numbers are bound to increase with more facilities being added

How to interpret the numbers?
The table shows the number of common user between individual facilities as well as between Lightsources (photon) and Neutronsources (neutron). For example, the ESRF lists 10287 active users. 433 of the ESRF users are also known as active users at ELETTRA. A total of 1313 ESRF users are also active users at at least one of the Neutronsources as shown in the row labelled neutron.

The last three rows show some numbers for all unique Neutronsource users; all unique Lightsource users; all unique users. For example we count 10023 Neutronsource users in total (last column), 25336 Lightsource users and 33025 users alltogether. There are 2334 unique users which use both Lightsources and Neutronsources. Remarkably, there is not a single pair of facilities without common users.

Where do our users come from?

Currently we count users with home institutions located in 82 different countries, including places like New Caledonia or Botswana.
 

 
 
The majority of the users are - little suprising - coming from Europe, but a significant fraction are coming from the United States, Canada, Australia or Japan, despite the fact that these countries provide similar facilities and instruments themselves. It clearly demonstrates the uniqueness and strength of the European Photon and Neutron research environment.
 

 

How often do users show up at the facilities?

Some users visit several facilites more than 30 times within 2 years, but the vast majority of our users show up at most twice in a 2 year time span. They are still using our services, submit proposals, access data or simply collaborate. This strongly emphaiszes the need for an advanced identity management and remotely accessible services of all kind. Roughly 1/3 of the users are first time users. Though results are still preliminary, that would indicate an increase of user in the order of 10.000 per year. To estimate the increase of active users more data are needed.

 

Gender and Age of our users

Roughly 30% of the users (with uniquely known gender) of the neutron and photon facilities are women, but for young scientists the ratio of female scientists is significantly higher. For 13% of the users the gender has not been recorded or could not be revealed, and roughly 5% appear as males in some databases and females in some others. The vast majority of the users are 40 years old or younger.
