Direct reaction and future spectrometer at HIAF

→Asia/Shanghai
Institute of Modern Physics, CAS, Huizhou, China
Description

The High Intensity Heavy-ion Accelerator Facility (HIAF) has completed its construction. Equipped with an advanced accelerator complex and a next-generation in-flight separator, HIAF provides an excellent platform for a wide range of experiments utilizing direct reactions. As an international user facility, HIAF warmly welcomes scientists from around the world to participate in its scientific programs.


Spectrometers play a pivotal role in direct reaction studies by enabling precise momentum analysis of outgoing reaction products, which is essential for both missing-mass and invariant-mass spectroscopy. To expand these capabilities, a dipole-magnet-based, large-acceptance spectrometer is planned at HIAF. Presenting these scientific opportunities to the broader community and gathering community input are vital steps in shaping the facility's roadmap. This workshop serves as the launchpad for the spectrometer's design phase, where contributions from researchers across diverse fields will be critical.


Following DREB 2026, this satellite workshop will bring together theoretical and experimental researchers to discuss recent progress with spectrometers and future perspectives in direct reaction physics. Discussions will focus on physics opportunities at HIAF, alongside the conceptual design, physics cases, and development plans for the future HIAF spectrometer.

Main Topics

• Direct reactions at HIAF and physics opportunities
• Experimental techniques and reaction theory
• Conceptual design and status of the future HIAF spectrometer
• Detector technology and instrumentation for direct reaction studies
• Future perspectives and international collaborations at HIAF

The program will take place from November 7 to 8, 2026, with participant registration on November 6. The presentation sessions and collaborative discussions will be held on November 7, followed by a guided tour of the HIAF facility on November 8.
