How to use electrodeless drift chambers in experiments at accelerators

Several types of wide-gap electrodeless drift chambers, including those with dimensions 1×1 m ², have been tested at accelerator beams. The chambers work with high efficiency (>99%), good spatial resolution ( σ = 0.2-0.4 mm) and good linearity at flux rates up to 2×10 ⁵ particles ^-1 per wire in spill, which corresponds to 3×10 ⁶ particles/s m ² on colliders. It is shown that at the proper mode of operation beam intensity oscillations within the range of up to 4×10 ⁵ particles/spill per wire do not affect the chamber efficiency.
