The MAX IV facility consists of a 3 GeV storage ring, a 1.5 GeV storage ring, and a linear accelerator (fed by two guns) that serves as a full-energy injector to the rings, but also as a driver for the Short Pulse Facility. The 3 GeV storage ring with a circumference of 528 m is geared towards hard x-ray users, while the 1.5 GeV storage ring (96 m circumference) serves soft x-ray and UV users. The 3 GeV linac operates at up to 100 Hz as driver for the SPF and injects into both storage rings at up to 10 Hz.

Machine operation schedule

A standard delivery week begins and ends at 08:00 on Monday. Monday 08:00 until Tuesday 07:00 is used for beamline characterisation and commissioning, and operational beam currents are not guaranteed during this time. Tuesday 07:00 until Wednesday 09:00 is reserved for maintenance and start-up activities on the accelerators. The remainder of the week is delivery to users at operational currents.
