The first Scientific Program Committee Meeting (SPC-1) for the 29^th Linear Accelerator conference (LINAC18) was successfully held at CSNS from December 15^th to 16^th, 2017. Fifteen linac experts from the world-renowned institutions and universities attended the meeting. Prof. Fu Shinian, head of Division of Accelerator Technology and co-chair of the SPC-1 meeting, hosted the guests.

Prof. Fu gave a brief report of the China Spallation Neutron Source (CSNS), and led a tour of the CSNS site for the guests. Prof. Yong Ho Chin, co-chair of SPC-1 meeting from Japan Atomic Energy Agency (JAEA), hosted the meeting and introduced the tasks of the meeting. The participants were then separated in four working groups and had two-day discussions.

The Linear Accelerator conference is a main bi-yearly gathering for the world-wide community of linac specialists. It provides a unique opportunity to hear about the latest advances of projects and developments concerning hadron and lepton linacs, and their applications.The purpose of the SPC-1 meeting is to select the candidate reports in LINAC18, which will be held at the campus in Institute of High Energy Physics in Beijing from September 16^th to  21^st, 2018.
