  • RF Sputtering AXPLORER (800/6) is a thin film deposition technique using a radiofrequency generator. RF Sputtering runs an energetic wave through an inert gas in a vacuum chamber which becomes ionized. The target material or cathode which is to become the thin film coating is bombarded by these high energy ions sputtering off atoms as a fine spray covering the substrate to be coated.

    Targets:

    Cu, Al, NiTi (51%, 49%), NiCr (50%, 50%) and Ti

    Gases:

  • laser 1

    Laser Specifications:

    • Source: KrF Excimer Laser
    • Wavelength: 248 nm.
    • Energy Density: 800 mJ/cm
    • Pulse duration: 24 msec.
    • Pulse Bandwidth: 300 pm.
    • Pulse Rate: 50 Hz.
    • Spot size (on target) :0.5 x 0.5 cm

    The laser beam is homogenized on a 1.6 x 1.6 cm area.

    Laser 2

    Computer-controlled stage capable of scanning 8" horizontally, with 50nm resolution and 4" vertically with 100nm resolution.

    Laser 3

    Projection lens reduces the spot size down to 0.5 x 0.5 cm.

    Laser 4

    The intensity of the beam is homogenized in the transverse direction using four arrays of cylindrical lenses. Two arrays, each of which is composed of ten vertical cylindrical lenses, to homogenize the beam in the horizontal direction. Whereas, each one of the two other arrays has ten horizontal cylindrical lenses to homogenize the beam in the vertical direction.

    Laser 5

    The telescopic lenses are composed of a horizontal cylindrical lens that shortens the long axis of the pulse and a vertical cylindrical lens to stretch the beam in the horizontal direction.

    Laser 6

    Attenuator is used to control the pulse energy from 90% to 10% of the maximum energy.

  • The Turbula shaker mixer is a 3-dimensional shaker/mixer for fast and homogeneous mixing of powder substances of different weights and particle sizes.

    Turbula Mixer 1

    Basic Principle:

    The Turbula shaker-mixer is used for the homogeneous mixing of powdery substances with differing specific weights and particle sizes. The mixing basket can hold any form of container from test tubes up to containers having a volume of 2 liters. The container is set into three-dimensional movement (a combination of rotation, translation, and inversion). The speed can be varied by adjusting the position of the drive belts on the 5-step pulleys.

    Applications:

    Powder blending:

    • Mixing extremely heavy powders with light ones
    • Minute quantities with huge volumes
    • Fragile granules without crumbling
    • Particles of different diameter - mixed to uniformity

    Other applications for the TURBULA include:

    • Ball Milling: Use grinding media inside mixing vessel to create an aggressive ball mill without corners or dead space
    • Sampling: Any single or multiple number of samples can be taken, each truly representative of the bulk

    Metal Finishing: Intricate precision parts can be debarred and polished without damage.
