Despite the variety of approaches only the methods using low energy secondary electrons emitted, when the beam passes through a thin target, found practical application. The most common beam instrumentation, based on this method, became Bunch Shape Monitor developed in INR RAS. The monitor provides direct measurements of bunch shape and bunch longitudinal halo, allows to carry out such complex diagnostic procedures as longitudinal emittance measurements, amplitude and phase setting of accelerating cavities and control of bunch shape evolution in time to check the overall quality of longitudinal tuning of the accelerator. The principle of the monitor operation, design features, ultimate parameters and limitations are discussed. Several modifications of the monitor with implementation peculiarities are described as well as lots of measurement results at different ion linacs with a variety of beam parameters. New challenges for bunch shape instrumentation to satisfy demands of forthcoming linacs are also characterized.
