New Applications

The intense heat and energetic particle fluxes expected in ITER and future magnetic fusion reactors pose prohibitive problems to the design, selection and maintenance of the first wall and divertor. Micropellet injection (MPI) technologies can offer some innovative solutions to the material and extreme heat challenges. Basic physics of micropellet motion, ablation and interactions with high-temperature plasmas and energetic particles are presented first. We then discuss MPI technology options and applications. In addition to plasma diagnostic applications, controlled injection of micropellets of different sizes, velocities and injection frequencies will offer several possibilities: (1) better assessment of the core plasma cooling due to dust produced in situ; (2) better understanding of the plasma–material interaction physics near the wall; (3) new methods for plasma fuelling and impurity control; and (4) techniques for edge cooling with minimal impact on the plasma core. Dedicated small-scale laboratory experiments will complement major fusion experiments in development and applications of MPI.

Microscopic Slide

In the last decade fine needle aspiraration biopsy has gained recognition as a valuable diagnostic technique, and its benefits have been demonstrated in large series of patients with almost every type of tumor (1,2). The usual way to collect cellular material from needle-aspiration biopsies is to discharge the needle and syringe contents onto a microscopic slide and smear the material with another slide. The entire specimen is contained on the slides prepared at the time of biopsy. Serious technical difficulties are inherent to this method. 1) Inconsistent fixation, 2) drying artifact, 3) loss of tissue fragments, 4) inability to confirm impressions by a “second method”, and 5) retention of significant diagnostic material in the needle hub. Our technique avoids these difficulties.
