FLAG STYLE SAMPLE PARKING STAGE

The Sample Parking Stage for ‘Flag’ style sample plates commonly used in surface analysis instrumentation, has been designed to accommodate Omicron, Specs and Aarhus Flag style sample plates.

It is intended to be used to store multiple samples in the UHV analysis chamber or the sample preparation chamber.

flamar-imgIt comprises a carousel plate or multiple carousels, each of which can accommodate 4 flag style sample plates. Each of the sample plates is held securely in place by a pair of springs holding them solidly in their docking station, such that there minimal risk of any falling out irrespective of the mounting orientation the Parking Stage.  The carousels are mounted from a magnetically coupled rotary drive (MagiDrive) such that each can be presented in turn to the transfer mechanism, whether that be a ‘Wobble Stick’, magnetically coupled transfer arm (PowerProbe) , or linear rack and pinion transfer device.

The whole device might also be suspended from a bellows coupled linear Z-shift (LSM) (typically 25-50mm stroke) to set the height or maybe move the carousel out of the way completely for access. Multiple carousels can be employed by being stacked vertically to provide additional storage, for up to 16 sample plates, in which case the linear motion option will almost certainly be necessary to access the different levels.

The device is fully UHV compatible and bake-able to 250oC

As with all UHV Design motion mechanisms there are various automation / motorisation options available for each axis of motion.

Accurate Tests in Vacuum

 Tool for proprietary calibration and testing of vacuum gauges   

Evatec-Fig1As a manufacturer of vacuum measurement instrumentation and service provider for other producers’ gauges we are regularly faced with the task of generating arbitrary vacua within a recipient and recording calibration values of the examined sensors. Four DAkkS- calibrated gauges serve as our references for pressure measurement over ten decades.

To solve this problem we decided to utilize the all-metal-variable leak valve 590 from VAT, which combines two distinguished characteristics: The excellent quality of VAT all metal valves, well known in XHV applications and large accelerator research, and the leading edge control technology, known from butterfly and gate valve systems in semiconductor and thin film production. With its hard-on- hard sealing diaphragm it enables pressure regulation for the whole vacuum range from rough vacuum to XHV while being simple to use and maintain.

TESTING for next voyage exploration to MERCURY

The system is designed to simulate environmental conditions of a space vehicle during the next exploration voyage to Mercury (BEPI Colombo Mission), in order to verify the behavior of antenna receiver materials. The particular requirement towards the testing system is to increase and maintain the surface temperature of a specific device under test (DUT) up to +550°C under high vacuum conditions.

fig2

The requested conditions have been reached by heating the target through infrared (IR) ceramic emitters. The IR emitters are mounted on six reflective panels placed all around the target specimen corresponding to the six faces of a parallelepiped. Each face is fixed independently to an external cylindrical structure and can be adjusted or opened in order to allow the user to access inside the test volume (Fig. 2).

Allectra continuing to invest in custom manufacturing capabilities

OLYMPUS DIGITAL CAMERAThe Allectra Group has this year continued to invest in its custom design and manufacturing departments in both the UK and Germany. The company has two facilities with both engineering and scientific capability providing customers with bespoke vacuum science solutions. The departments incorporate a drawing office with the latest software including 3-D modelling, clean assembly area and specials workshop. They are staffed by a skilled team of physicists, technical advisers, engineers and specialist project managers. These departments also work closely with Allectra’s own Research and Development team.

Allectra has invested in machining capabilities as well as installing a new four-stage automatic ultrasonic cleaning plant, which can clean products to our Ultra high-vacuum standard (10-11 mbar). Recent releases from our custom manufacturing team include a Multi-feedthrough component featuring 11 15-way Sub-D feedthroughs, 2 High Voltage 12KV double-sided MS style feedthroughs, 2 High Voltage Coaxial feedthroughs and water cooling feedthroughs for the Semi-Conductor sector, and a vacuum plate to house 156 Allectra Sub-D feedthroughs for an in-vacuum X-ray detector for a major synchrotron.

Angelantoni Test Technologies And Highly Accelerated Life Testing

Reliability is a key factor for product durability and for competitiveness in the global marketplace. Both the user and the manufacturer gain from higher reliability.  The user has a product that does what it is supposed to when it is supposed to without failure.  The manufacturer has lowered production costs and fewer product returns.  Everyone wins.

At ATT, we have combined more than 70 years of experience in the design and manufacture of environmental test chambers to provide a state-of-the-art system capable of providing the user with the best performance in the reliability growth process.

New technologies for enhanced environmental testing on spacecraft structures

Al SSMET 2014 (European Conference on Spacecraft Structures, Materials & Environmental Testing) tenutosi a Braunschweig in Germania, ACS – società del gruppo ATT – ha presentato tre approcci costruttivi per la realizzazione di camere da vuoto rispondenti a diverse esigenze di Ricerca e Sviluppo in questo settore:

  • test di sistemi di propulsione spaziale, come i propulsori ad effetto Hall
  • incremento della temperatura superficiale del DUT (dispositivo in prova) fino a +550 ° C
  • installazione di un sistema solare all’interno della camera da vuoto (TVC)

 

Ogni applicazione implica problematiche specifiche che devono essere gestite dalla camera da vuoto durante le prove. In particolare, l’emissione di gas ionizzato ad alta energia ad alte temperature, le temperature superficiali superiori a 800 K e la contaminazione ottica del provino rappresentano sfide significative per apparecchiature di prova in cui si ricreano le condizioni di alto vuoto.

Pompe NEG per apparati da Ultra ed Estremo Alto Vuoto

Introduzione

Molte applicazioni industriali e di ricerca di base richiedono la produzione e il mantenimento di ultra alto vuoto (UHV) o addirittura di estremo alto vuoto (XHV). I sistemi di pompaggio utilizzati per ottenere queste condizioni sono vari: pompe turbo molecolari, pompe criogeniche, pompe ioniche, generalmente utilizzati in combinazione con sistemi di pompaggio primari (ad esempio le pompe rotative o roots) che ne consentono l’innesco. In UHV/XHV, queste pompe possono presentare in alcuni casi limitazioni specifiche quali:
