No, x-rays and gamma rays cannot be focused by lenses or conventional telescope mirrors. To make mirrors that will focus x-rays or gamma rays you need very shallow glancing angle mirrors, that are nearly just parabolically tapered tubes. Typically several of these tubes with the same focal point but different diameter are nested inside each other.
Gamma radiation is very penetrant and is used in medicine, nondestructive testing, etc.
They use telescopes, but different types of telescopes. There are telescopes for radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays, all depending on what it is you're trying to see.
No they do not, or use gamma ray telescopes either. Not ground based.
By X-ray film or some kind of detector that is the digital equivalent.
Telescopes come to mind. There are many types of them ranging from one end of thee-m spectrum to the other. There are ultraviolet, visible light, infrared, microwave radio wave and gamma ray telescopes to name a few. With these telescopes other devices are used. CCD's and sometimes photographic film cameras to record images, computers to control the cameras and telescopes. Also used in conjunction with the recording devices are filters, both optical and electrical, and notch and bandpass.
Gamma, X-ray, Optical, and Radio
The three major types are the optical, the infrared, and the radio telescopes. There are other specialized instruments for observing gamma rays, or x-rays, or for doing processes such as interferometry. Among the optical telescopes are the refracting (lens), reflecting (mirror) and compound telescopes (computer-assisted combinations of several smaller telescopes to simulate a much larger one).
An "optical" telescope would naturally collect light from optical wavelengths, meaning visible light from ~400-800nm.

The earth's atmosphere doesn't let these rays reach the ground, so the telescopes are placed in orbit where they can receive the rays.

Optical measures visible light, Radio measures electromagnetic radiation in that part of the spectrum corresponding to radio waves. Same with X-ray telescopes and x-rays. Optical is the kind you look through.
