An object of the present invention is to provide an extreme ultraviolet light source target which can emits extreme ultraviolet light with high emission efficiency. A solid target made of heavy metal or heavy-metal compound and having a density 0.5 to 80% that of the crystal density is used. When the target is irradiated with a laser beam, plasma of the heavy metal contained in the target is generated, and extreme ultraviolet light having a predetermined wavelength which corresponds to the kind of the heavy metal is emitted from the plasma. When the density of the target is made to be smaller than the crystal density as described above, space distribution of the density of the generated plasma can be controlled, and the region in which plasma absorbs energy of the laser beam overlaps the region in which the plasma emits the extreme ultraviolet light. Thus, emission efficiency can be improved, preventing energy loss. For example, in a case where the SnO2 target having a density 24% of the crystal density is used, the emission efficiency at around 13.5 nm wavelength is higher than in the case where a Sn crystal target is used.

The invention discloses a method for blocking and storing a stored file in a cloud storage system by adopting a dynamic adaptation method, and mainly aims to solve the problems of low space utilization rate and disk fragments caused by the use of a fixed block size in the prior art. The implementation scheme comprises the following steps of: setting a grouping factor vector by using the cloud storage system, obtaining the size and heat mark of a file when the file is to be stored, and when the size of the file is smaller than a minimum grouping factor, using the final size of the file; if the heat mark is 1, copying and storing the file, and on the contrary, directly storing the file on a single node; and when the size of the file is larger than the minimum grouping factor, comparing the size of the file with a grouping factor to obtain an optimal block size. Compared with the method using the fixed block size, the invention has higher file uniformity, can better solve a load balancing problem caused by hot files, and is particularly suitable for the cloud storage system.

Ultraviolet pulse laser with 16-29j / cm2 of low-energy density and 60-90kHz of high repetition frequency is adopted to cut and process PI (polyimide) substrate at 100-400mm / s scanning speed, then ultraviolet pulse laser with 113-226j / cm2 of high-energy density and 20-30kHz of low repetition frequency is adopted to cut and process copper foil material at 50-200mm / s scanning speed, and the ultraviolet pulse laser is closed when no copper foil material exists, until the copper foil material is penetrated in a cutting manner, so as to carry out FPC (flexible circuit board) golden finger cutting and processing procedures. In the method, the method that the ultraviolet pulse laser with high-energy density and low repetition frequency only cuts the copper foil material and the method that the ultraviolet pulse laser with low-energy density and high repetition frequency only cuts the PI substrate are combined to cut the substrate of the FPC, so that heat damage, carbonization and chippings at the cutting edge of PI can be effectively avoided, the cutting quality of the golden finger is improved and the problems in the prior art are solved.
