=================================================================================

TEM specimen holders can be damaged, for instance, due to improper installation of specimens. As an example, Figure 2770 shows a good JEM JEOL double tilt holder and a similar but destroyed double tilt holder. A spring for supporting the y-tilt and the two screws for the specimen support were broken due to improper installation of a specimen or during pulling out the holder from the TEM system if the tilted holder had not been neutralized. The cost of repair can be very high, e.g. $ 3,000 to 5,000 for a single repair of a double tilt holder is very normal. Fortunately, some holders, e.g. single tilt holder, are not so easily damaged.
