Sub-millimeter positioning system for proton therapy treatment of ophthalmologic tumors.
For tumor treatment, radiotherapy frequently uses electrons or X-ray beams. Those techniques do not offer optimal results for deep tumors and can even irradiate healthy or radio sensitive tissues located close to the tumor, with possible collateral damages for the patient.
Proton therapy offers new opportunities for the treatment for tumors nearby sensitive organs, particularly in ophthalmology.
The unique advantages of a proton beam are its low divergence and its ability of focusing exactly onto the target for a maximum power dissipation on the tumour, not on its neighbourhood.
It is therefore highly important to perfectly align the patient with the proton beam.
WOW Company has developed a 3-axis accurate positioning seat able to fulfill this requirement.

The double tilt translator DTT is based on 2 pairs of APA 35XS. Three types of movement can be generated:
* Z movement (translation)up to 35 µm, when the two pairs of APA 35XS are simultaneously actuated

Flexure guided piezo stage positioners are used in a variety of applications from semiconductor manufacturing to precision machining.
PI introduced the first line of piezoelectric actuators more than 35 years ago. The technology's unique features such as: responsiveness; stiffness; life time and infinite resolution, have opened many markets since then, from semiconductor testing to precision machining. Typical piezo tools for precision machining are equipped with special waterproof casings which also provide the mechanical interface to the tooling machine and the tool servo.
Integrated metrology systems feature resolution in the nanometer and sub-nanometer range for closed-loop operation with digital or analog motion controllers. Flexure guiding mechanisms and motion amplifiers provide long traveling ranges and protect the piezo ceramics from off-axis forces.
PI piezo actuator systems are used throughout the world, often in applications that run 24 hours a day, seven days a week. They improve the manufacturing precision of optics, crank shafts, bearings, cylinders, pistons, etc. in crucial processes such as diamond turning, milling, grinding, out-of-round boring or wear-compensation of tools.
Custom-manufactured high-performace piezoceramic actuators provide lifetimes of billions of cycles. Power amplifiers with energy recovery and 2000 W peak power are available for high-dynamics applications.

piezosystem jen's new nano-positioning stages of the series nanoX work in a bidirectional active manner. Hence, these elements are well equipped for fast dynamic applications combined with an excellent guiding accuracy even at high mass loads.
What does this mean? Due to the inability of the smca (stacked multilayer ceramic actuator) to generate pull forces, state-of-the-art piezoelectric driven nanopositioning actuators show different kinds of behavior depending on the sense of direction of their stroke. Hence, the resulting forces in the push direction are determined by the high force generation of the actively controlled scma. The pull force is determined by the weak spring reset force of the passive acting flexure hinges. Both result in a push/pull-force ratio of up to 10. The dynamical performance, load capacity and robustness of the whole nanopositioning assembly are limited by the behavior of the weaker sense of direction.
Psj's new sophisticated gear design operates in a bidirectional active manner which reduces the push/pull-force ratio to up to approx. 1:1 (without affecting the trajectory). Both stroke vectors of the nanopositioning stage are controlled by the high pressure force generation of the smca's.
This mechanical design features:
the most efficient way to change the smca forces into translation power
an outstanding damping ability of actively controlled acceleration and deceleration
high inertial preload; a high degree of mechanical resistance against shocking overloads
minimized failure rate caused by the absence of destructive pull forces acting on the smca
excellent temperature compensation

PSE3xxx positioning systems make it easy to activate positioning and auxiliary axes automatically: halstrup-walcher presents a supplementary line of products housed in stainless steel for use in clean rooms and for applications in the food and beverage industry.
For production and assembly stations that accommodate various formats, manually positioning equipment can consume a great deal of the overall production time depending on the quantities to be produced and the amount of variation in a given product. Because they can be set to operate automatically without the use of a hand wheel, intelligent positioning systems represent a convenient alternative. Designed as a complete solution with a brushless DC motor, these compact halstrup-walcher instruments also include a gear, controller and absolute measuring system.
As a supplement to the successful PSE 3xx series, models are now available as well in round stainless steel housing (protection class IP 68). The units can be washed and are resistant to liquids like lyes, making them perfect for use in the food and beverage industry. These models are especially suitable for clean rooms, as personnel no longer need to enter the rooms to adjust machine positioning, thereby eliminating the need for subsequent sterilization.
The integrated electronic control feature frees up the machine's central control unit. No external motors, proximity and limit switches, pulse generators or encoders required. The hollow shaft and adjustable collar make these units easy to assemble. The unit is operable as soon as it is hooked up to a 24-volt power supply and data link (via CAN bus, Profibus or DeviceNet).

Intelligent positioning systems for the food industry and clean-room applications - Say good-bye to the hand wheel
PSE3xxx positioning systems make it easy to activate positioning and auxiliary axes automatically: halstrup-walcher presents a supplementary line of products housed in stainless steel (protection class IP 68) for use in clean rooms and for applications in the food and beverage industry.
For production and assembly stations that accommodate various formats (longitudinal and horizontal construction; 30 or 50 W), manually positioning equipment can consume a great deal of the overall production time depending on the quantities to be produced and the amount of variation in a given product. Because they can be set to operate automatically without the use of a hand wheel, intelligent positioning systems represent a convenient alternative. Designed as a complete solution with a brushless DC motor, these compact halstrup-walcher instruments also include a gear, controller and absolute measuring system. The integrated absolute measuring system eliminates the need for a time-consuming reference run. Connecting to a bus system (CAN-Open, Profibus PD or DeviceNet) simplifies the wiring. A hollow shaft with adjustable collar or an output shaft external square 10mm makes assembly quite simple. This positioning system is particularly suitable for automatically adjusting the positions of filling and packing machines in the pharmaceutical and food industries. Its stainless steel housing makes the PSE series ideal for use in clean rooms or for sterile filling processes.

Intelligent positioning system PSE 3xx from halstrup-walcher
Positioning for auxiliary and positioning axes
Small lot sizes and a variety of product types require positioning and auxiliary axes to be flexible. Intelligent positioning systems are putting things in motion in cases where the traditional hand wheel was once all you needed.
Changing workpiece formats and repositioning die carriers are typical applications for the PSE 31x positioning systems with brushless DC motor. Designed as a complete solution, these compact instruments include a motor, gear, controller and absolute measuring system as well as a serial interface. This design allows the integrated electronic control feature to free up the machine's central control unit. No external power sections, proximity and limit switches, pulse generators or encoders required. Also, mounting these positioning systems is easy, thanks to a hollow shaft and adjustable collar requiring the operator merely to tighten a single screw. The unit is operable as soon as it is hooked up to a 24-volt power supply and data link. Existing equipment can be retrofitted simply by replacing the hand wheel, a modification that, due to the compact construction of the unit, can generally be accomplished without making any changes to the machine itself. halstrup-walcher offers PSE 31 positioning systems in three sizes: 1, 2 and 5 Nm.
