Diamond milling

MAGIC incorporates many technological innovations in order to fulfill the requirements imposed by the physics goals. The telescope is installed at 2200 m above see level on the Canary island La Palma (Spain). The 17 m diameter tessellated reflector dish consists of 964 0.5 x 0.5 m2 diamond milled aluminum mirrors. The parabolic reflector shape conserves the time structure of the Cherenkov pulses to increase the signal-to-noise ratio with respect to the night sky background. 

UltraprecisitMi cutting is subdivided into diamond turning and diamond milling (fly-cutting).

FIGURE 2.2 (a) Particle size distribution for three different NiO powders used in the Ni-YSZ cermets the circle is for a commercial NiO powder with 0 h milling, the diamond is for the commercial NiO milled for 138 h, and the square is for the NiO powder prepared by the GNP process, and (b) resistivity versus Ni volume percent for the Ni-YSZ cermets made with the three different NiO powders at 1,000°C in reducing atmosphere. The YSZ powder has grain size of 0.1 to 0.2 pm, and the cermets were all sintered at 1,400°C for 2 h.

Austin Powder Co, Cleveland, Ohio was established in 1883 under the name of Austin Black Powder Mills by L. Austin(18l7-1887) and his brothers (Ref 1). The plant manufactures mining expis among them "Austin Red-D-Gel" (gelatinous permissible expis) and "Austin Red Diamond" (nonge latino us permissible expl) (Ref 2)... 

The formation potential is usually negative for nPs = 1, and therefore positronium emission is allowed. However, with the possible exception of a diamond surface (Brandes, Mills and Zuckerman, 1992), it is positive for nPs > 2, which therefore precludes the emission of excited state positronium following positron thermalization in the material. 

Micro milling was applied frequently in many early applications of micro structuring. Microfabrication of the parallel channels was performed by micro milling of metal tapes at the Karlsruhe Research Center (Forschungszentrum Karlsruhe) [138], In the case of aluminum alloys, ground-in monocrystalline diamonds were used [139], In the case of iron alloys, ceramic micro tools have to be used owing to the incompatibility of diamonds with that material [44], It is certainly a useful tool for experimental work and rapid prototyping, but not a choice with respect to future mass production.
