In the anniversary year >> 50 years of NTG << the NTG organized its 2nd International IBF Conference with 70 participants from 10 countries.

Many high-ranking speakers presented innovative ideas and novel areas of application for our IBF and IBE systems.

In addition to the interesting lectures, there was also enough time for the experts in their field to exchange ideas, which resulted in further trends in IBF and IBE development.

After all the knowledge exchange, the celebration should of course not be neglected. At our Oktoberfest there was hearty feasting, lively dancing and joyful celebrations.

We are already preparing to host the 3rd international NTG IBF conference in 2022. For more information, follow one of our next posts. We hope that we will then again be able to welcome experts from many countries to revive the international exchange from person to person.

We look forward to you!

In addition to the previously introduced new developments in the field of ion beam processing and ion sources, our standard ion sources RF40 and RF60 provide excellent service. Both systems are rf-driven ion sources with argon as the standard working gas. By avoiding electrodes in the plasma region, the ion source is very stable over the lifetime and requires less maintenance. The FWHM width of the gaussian ion beam is adjustable in the range from 0.5mm up to 30mm. The peak removal rate is up to 12nm/s with respect to quartz as the material to be processed. Alle values are depending on the selected configuration, which is realized by different extraction system or aperture systems.

To neutralize the charge of the ion beam during processing, a hot cathode neutralization system is used, which emits electrons to compensate the positive charge of the ion beam and prevent charging effects on the surface of the workpiece.

Design, fabrication and on-site installation were part of this project.

This is a system for the 1PW test area with steering and focusing optics.

The system consists of 3 chambers. Two large, height adjustable rectangular chambers made of stainless steel, one chamber is a single piece and one is a two piece chamber. The third chamber is a large 8-cornered chamber made of aluminum. The chambers are designed for a final pressure of ≤ 1 * 10-6. Furthermore, optical tables (breadboards) for each chamber which are mechanically decoupled and adjustable in X, Y and Z direction independently of the chambers, beam tubes to connect the chambers, various vacuum slides, without vacuum system.

Inside, there are mirrors mounted in micrometer-precise positioning systems (translation and rotation) that direct the laser beam to the appropriate experimental areas.

In the field of beam diagnostics, a new test method has been established at NTG. For the second time, we are supplying capacitive position probes, in one case Beam Position Monitors and in the other linear-cut Shoeboxes, which have been calibrated by means of a wire with a high-frequency alternating voltage. The operating principle of these probes is based on the influence of a charge displacement on the electrodes which are symmetrically arranged around the beam. This charge displacement can be measured as an electric current. If it is the same on the corresponding electrodes, the beam is on the axis of symmetry. Due to the design and for manufacturing reasons, the geometric axis of symmetry is not always exactly on the electrical symmetry axis. Our new test method measures exactly this deviation. The electromagnetic field of the wire simulates the field of a beam of charged particles (ions, electrons). Via the exact position of the wire, we obtain the desired information about the symmetry ratios. But be careful, with such high precision requirements, possibly the changed boundary conditions in the final installation situation must not be neglected. Often there is an acute lack of space and the diagnostic elements have to be adapted accordingly. This means that the sensitive probe elements tend to move to the periphery of the unit and thus become sensitive to the environment. Here, constructive measures may have to be taken in advance or, if possible, calibration in the final installation situation is recommended. We will be happy to advise you on the specific application.
