R9plus: Ultimate SPM Control

R9plus

BUILT for a PURPOSE: Your Research, Your Success
When you are pioneering the frontiers of Nanoscience, you can count on RHK’s new R9plus SPM Controller to lead the way. Its remarkable advancements originate from direct user feedback, RHK’s Technical Advisory Board, and our own top scientists.

Explore with Confidence
With the plus Advantage, no Controller is better equipped or more capable to take on any research challenge you face.

History behind R9plus
RHK’s original R9 brought great new capabilities and fresh thinking to the SPM field worldwide. It even forced design re-thinking in our competitors’ systems. Although they tried to catch up, they couldn’t match up to R9.

Meanwhile, our continuous improvement process evolved R9 well beyond our prior breakthroughs and achievements. With so many new capabilities and ever-improved, ever-expanding firmware, a new model emerged. This is R9plus.

While we pledge our continued support for existing R9 units and customers, we proudly announce our new R9 successor: R9plus.

With R9plus, RHK sets the standard as the Innovation Leader for SPM Control. Over 1,000 RHK original “Blue Box” Controllers were installed worldwide. Then we revolutionized the field with R9 integrated Controllers. More than 225 R9s are producing published results today. Now, RHK surpasses the market yet again with R9plus.

Uniquely integrated in one box, R9plus unites near-limitless flexibility and power with thoughtfully designed single-click simplicity and rock-solid stability. R9plus’s refined and expanded firmware, software, and even further improved analog circuitry give you highest performance and confident command.

Only from RHK The Innovation Leader

We really appreciate the strong flexibility of the R9. Our microscopes require very different driving signals.

The R9 can support those requirements easily by simply reorganizing theIHL file. There are so many high voltage output ports. The most important is that all of those outputs are independent. Even for very complicated operation, it is very easy to be realized.

Dr. Haibiao Zhou University of Science and Technology of China, Hefei, China

The R9 is a very powerful digital SPM controller.

Very easy to use. When acquiring spectroscopy, a lot of flexibilities with a very precise adjustment of the tunneling junctions.

Dr. Jindong Ren/ Prof. Haiming Guo Institute of Physics, CAS , Beijing, China

.. the surprising flexibilities of the R9 IHDL software.

This makes the experiment very flexible. All
the functions we need can be realized by slightly modifying the IHL file.

Dr. Kai Chang / Prof. Qikun Xue Department of Physics, Tsinghua University, Beijing China

The R9 controller is working great for us.

The internal lock-in has stability and resolution which is comparable to the industry standard SRS 830 and for us that is a big plus of R9. Another plus of R9 is the convenience of use.

Dr. Pratap Raychaudhuri Tata Institute of Fundamental Research, Mumbai India

Thanks for being so prompt and continuing to work on this.

You guys are the best company I've interacted with in a long time.

Blake Birmingham Baylor University

The transient recorder on the approach procedure is great

I was able to see how much feedback leads to ringing the tip against the sample surface in just a couple minutes

I was able to see how much feedback leads to ringing the tip against the sample surface in just a couple minutes, which is exactly what I wanted to know.  I’ll try to play with some of the other new things I see in the dashboard over the next couple weeks, but this alone should be a tremendous help in protecting some of our more valuable probes.

I am very happy with R9, “it just worked”.

I got atoms right away, even in ambient conditions

Joe Smerdon University of Central Lancashire, UK

My experience with RHK has been very positive.

Working directly with an RHK engineer, I was able to customize an STM system for the types of experiments that I want to conduct.

Working directly with an RHK engineer, I was able to customize an STM system for the types of experiments that I want to conduct. I appreciate the flexibility on the part of RHK to work within the constraints of my start-up budget, allowing me to begin my experiments with a state-of-the-art
STM system with the ability to add capabilities (e.g. vacuum system, cryogenics, etc.) at a later time as funding becomes available. Everyone at RHK has been extremely responsive to questions I have had spanning from questions about software functions, the ability to customize measurements, electronics, hardware, and inquiries for new system components and upgrades. I have and will continue to highly recommend RHK to other researchers looking to construct a high-quality STM system and who would like to work with a company which is very responsive to their questions and needs.

We are still at the early stages of using the R9, but something that we observed right away was that there was a significant improvement in the signal to noise.

We take friction images all of the time and these can be looking at very small scans that are just a couple nanometer scan sizes.

We take friction images all of the time and these can be looking at very small scans that are just a couple nanometer scan sizes. This means you’re really subject to limits that show up from any noise source including electronic. We saw that there was a significant improvement in the noise level and a significant improvement in bandwidth as well.

The students have been taking it for a test drive and they have insisted that they wanted to stick with it as they were getting better data.

My experience with RHK has been very positive, far beyond typical interactions with an instrumentation company.

We use the RHK Beetle instrument for nanomechanics and nanotribology research, and it truly is a workhorse instrument for us.

We use the RHK Beetle instrument for nanomechanics and nanotribology research, and it truly is a workhorse instrument for us. One thing that we do quite often, because we’re measuring things like friction and adhesion, is use customized scanning modes. We have been very happy with RHK’s support. We call them frequently and we’ve received a consistent and insightful support and feedback on how to implement and make use of very unusual customized modes that come up all of the time in research.  Our Beetle system with R9 is versatile, has powerful capabilities and high precision that coupled with excellent service. It has provided results that we have published in the top journals including Science and Nature. They have been a true partner in not just providing great instrumentation but giving excellent service and supporting further experimental innovation.

Professor Rob Carpick (2016)

No other STM controller we looked at provided the degree of flexibility the R9 offers, especially concerning user control of the high-voltage amplifiers

i.e. the relatively unique setup of our self-made STMs requires the Z-scan high voltage amplifier to be able to generate user-defined arbitrary wave forms, which at the point of purchase no other company wanted to guarantee.

i.e. the relatively unique setup of our self-made STMs requires the Z-scan high voltage amplifier to be able to generate user-defined arbitrary wave forms, which at the point of purchase no other company wanted to guarantee. The R9 works flawlessly in this regard, so I’m convinced we made the right choice to buy the R9.

Great experience with the tech support of our SPM1000 also heavily influenced our decision to buy RHK again.

Simon Diesch (2016)

The specs of R9 were too good (v Nanonis) to pass up, and I have not been disappointed.

I am using the pulse counter, PLL, and lock-ins for an eventual experiment that will combine confocal and AFM for extremely high res MFM measurements. The R9 has moved a step beyong Nanonis.

Chris Mellor Univeristy of Nottingham, UK

When it comes to high resolution SPM measurements with operation at the physical limits

The SPM controller is a crucial component where one should not make any compromise but chose the best available technology.

The SPM controller is a crucial component where one should not make any compromise but chose the best available technology. The R9 provides superior stability and noise figures for the output channels controlling the tip movement and approach and super performance with unmatched digitization accuracy for the input channels. Together with the rich functionality and flexibility of the controller software as well as the ease in integrating external components, the R9 is the unrivalled choice for the ambitious SPM experimentalist.
