ILC++: an opportunity for all kinds of experiments

by Hitoshi Murayama

The ILC as it is planned today will offer a host of possible physics studies, writes Hitoshi Murayama, Director for Physics and Detectors in the International Development Team for the ILC. He asks: But why stop there? What else, however fancy it may seem now, can you see the ILC doing – fixed-target experiments, experiments at the beam dump or or near the interaction point? Now is the time to propose them!

Two workshops 2021 – Please mark your calendars

by Tatsuya Nakada, Hitoshi Murayama and Steinar Stapnes

The 2021 International Workshop on Linear Colliders (LCWS 2021) will be arranged by Europe/CERN as a remote meeting from15 to 19 March  next year. Similar to the past meetings, it will cover the physics, detector, and accelerator studies of ILC and CLIC. The meeting will be at a timely moment since the European Strategy for Particle Physics Update has been published and its implementation started. Also, the ILC International Development Team and its working groups have been set up and detailed plans for the ILC Pre-lab are being made. In parallel, the Snowmass process is on-going. This workshop will be followed by individual more specialized ones for ILC and CLIC in the autumn 2021. We are looking forward to “seeing” you all in March.

The ILC International Development Team (IDT) will hold a workshop, Towards ILC Expressions of Interest, in October 2021 in Tsukuba, Japan, with focus on the experimental programme of the ILC. The main meeting will take place from 26 to 29  October with an optional tour to the ILC candidate site in the Tohoku region of Japan, as well as satellite meetings before and after the main meeting. The discussion will be centred around the steps toward the Expressions of Interest for the experiments at the ILC. It will also include discussions of recent developments in detector technology and provide updated information about the Pre-lab planning and the general status of the ILC project. Further details will follow soon.

    On 10 September the International Committee for Future Accelerators (ICFA) announced the structure and members of a new organisational team to prepare a “pre-laboratory” for an International Linear Collider (ILC) in Japan. The ILC International Development Team (ILC-IDT), which consists of an executive board and three working groups governing the pre-lab setup, accelerator, and physics and detectors, aims to complete the preparatory phase for the pre-lab on a timescale of around 1.5 years.

    It is remarkable to note that the total number of such TESLA-style cavities installed or to be installed in presently approved accelerators is more than 1800. Were a 250 GeV ILC to go ahead in Japan, approximately 8000 such units would be required.
