The 52nd ICFA Advanced Beam Dynamics Workshop on High-Intensity and High-Brightness Hadron Beams (HB2012) took place from September 17 to 21, 2012, in Beijing, China. The workshop was hosted by Institute of High Energy Physics (IHEP), CAS, and is a continuation of the successful biennial HB workshop series started about ten years ago (2002 at Fermilab, 2004 at GSI, 2006 at KEK, 2008 at ORNL and 2010 at PSI).

HB2012 keeps the traditions in the workshop series to provide a platform for presenting and discussing new progresses, status and future developments of high intensity and high brightness hadron beams, including beam physics in circular and linear hadron machines, technical systems and accelerator projects (under construction or in design) around the world. The workshop venue was in Park Plaza Beijing West Hotel, and a tour to IHEP accelerator facilities and development laboratories was arranged in the afternoon of the last day, which include Beijing Electron Positron Collider (BEPC), prototypes for China Spallation Neutron Sources, the R&D RFQ for ADS and the IHEP workshop. There were 175 registered participants, comparable to HB2010 but more than previous HB workshops.

The five-day workshop began with a plenary session comprising eight invited talks and followed by a poster session in the second half of the afternoon. The following three days were dedicated to two parallel sessions organized by five working groups, which include ninety talks and working group discussions. The most of the oral presentations were invited by the working group conveners, and the contributed ones were selected from the submitted abstracts. On the last day, summary talks were presented by the working group conveners. 

Following its precedent HB workshops, HB2012 proved to be a successful and fruitful workshop that highlighted the rapid and comprehensive progress made in high-intensity hadron accelerators from around the world. With new projects evolving, the growing interest in the field is further made evident by high participation at the HB series.

The proceedings, which include copies of presentations are available are available on the JACoW website. Selected papers in extended versions after peer-reviews are to be published in a special edition of Physical Review Special Topics – Accelerators and Beams.

During the IOC meeting at HB2012, the next HB workshop (HB2014) was determined to be held in October or November 2014 in MSU, East Lansing, USA. It follows the tradition of the HB workshop in every two years and rotating among three regions: Europe, Asia and North-America.

We look forward to seeing you in East Lansing in 2014.
