AbstractWith the program system FAST-STEP the temporal step-by-step disposal procedure of a HLW repository and its finite geometry can be taken into consideration in the calculation of the time and space dependent temperature distribution. This will be obtained through the application of a suitable coupling of calculation models treating both far field and near field phenomena.After the description of the single steps of the program system the influence of both aspects on the temperature distribution will be demonstrated with the aid of a test calculation. The possible fields of application of FAST-STFP will be pointed out at the end.

Near Field Scanning

In general, conventional methods of optical imaging are limited in spatial resolution by either the wavelength of the radiation used or by the aberrations of the optical elements. This is true whether one uses a scanning probe or a fixed beam method. The reason for the wavelength limit of resolution is due to the far field methods of producing or detecting the radiation. If one resorts to restricting our probes to the near field optical region, then the possibility exists of obtaining spatial resolutions more than an order of magnitude smaller than the optical wavelength of the radiation used. In this paper, we will describe the principles underlying such "near field" imaging and present some preliminary results from a near field scanning optical microscope (NS0M) that uses visible radiation and is capable of resolutions comparable to an SEM. The advantage of such a technique is the possibility of completely nondestructive imaging in air at spatial resolutions of about 50nm.
