The European Spallation Source ERIC (ESS) and Uppsala University are organizing an International Workshop on
Upgrading Existing High Power Proton Linacs
to be held in the Tänkartanken Seminar Room at the premise of ESS at Tunavägen 24, Lund, Sweden 8-9 November 2016.
The workshop will address the possibilities and limitations for further increasing the power of existing linear accelerators.
Increasing the strength of the accelerating field or increasing the pulse current will increase both the instantaneous and average beam power.
Increasing the instantaneous power only may be done by using an accumulator ring to compress the pulses which requires the acceleration of H- ions in the linac. The need to accelerate H- ions might in the longer term be alleviated by using a Fixed-Field Alternating Gradient Accelerator (FFAG) ring as accumulator ring.
Increasing the average power only can be made by by increasing the pulse repetition rate or increasing the pulse length.
The workshop will consist of the following four half-day sessions:
1. Pulse compressor rings
Session chair: Elena Wildner CERN, elena.wildner@cern.ch
2. Increasing the accelerating field strength, the pulse current or the beam energy
Session chair: Frank Gerigk CERN, frank.gerigk@cern.ch
3. H- sources and H- acceleration in proton linacs
Session chair: Alessandra Lombardi CERN, alessandra.lombardi@cern.ch
4. Increasing the pulse repetition rate or the pulse length
Session chair: Mark Middendorf SNS, middendorfme@ornl.gov
There will be invited and contributed talks and ample time for discussions. Registration for participation in the workshop is free and open till 15 October 2016.
Applications to give a contributed talk of 15(talk) +10 (discussion) minutes at the workshop, containing the title and a brief abstract of the talk, should be emailed to the appropriate session convener (see above) by latest 15 October.

In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.
