Possible cell phone interference with hybrid detectors

Hi all,
    Our Leica SP8 has a pair of HyD detectors, and I've noticed recently that we will get a series of saturated lines during a scan at random, intermittent moments.  Judging by their appearance, my guess has been that the detectors were picking up cellular data transmissions.  Every time I saw them, someone had a cell phone on them, and having them move the cell phone to the far side of the room, or turning the cell phone off, stopped the lines from occurring.  

    I was wondering if anyone else has noticed this with hybrid detectors, and whether this is normal behavior or something we need to have looked into.

Thanks,
    Ben Smith

Hi Ben,

We were warned by the Leica guys not to use cellphones anywhere near the
scan head on the SP8 - in fact it has a great big picture of a cellphone
with a line through it on the scanhead! - so I guess it is a well-known
problem, not a special "feature" of your system.

Best wishes,
Alison

Hi Ben

We have the same problem with one of our sp5 systems that has HyDs on it. Every once in a while you see a saturated line across the image. We have been careful with cell phones around the system, but these lines tend to happen anyway every once in a while. We had them happen just from a door opening or closing on the room. My impression is that while cell phones could be part of the problem, they are probably not the only ones. There could be plenty of equipment or anything else in the room that sometimes interferes. We have these lines very rarely, but I can't think of a scenario where they are completely guaranteed not to show up.

That being said, we have two other inverted systems, an sp5 with 3 HyDs and an SP8 with 2 HyDs. We never see any interference  lines on these systems, no matter what is going on in the room. My theory is that the HyDs on the inverted scanheads are hidden away towards the rear of the microscope and are perhaps better shielded from interference then those on the upright system, where they are just sticking out in the open. I communicated this theory to Leica, and they said that this could potentially be an explanation, but they haven't yet come up with any idea for potential shielding of them.

Hope this helps,
Yevgeniy

You could try to shield them with aluminum foil. I tried that to find a interference source on a different system and it worked!

We have a similar array of detectors on an SP5: we DO get cell phone (when
they work..) interference and Leica got us some 'no cell' stickers/warnings
to be placed in the room, right when we had the system installed.

Yes, we were advised this would be a problem, and have a cell phone bucket
outside the door where people have to leave their phones...

Hi out there

Same experience for us. We were getting random interference lines from our bright field detector on a NikonA1. It was not linked to cell phones though but from the cables of another system that stands very nearby. Shielding the cables with alu foil worked a charm.

Lead foil bags, such as the ones we used to use for protecting film from X-rays in airports, wrapped around the PMTs should solve this problem.  Don't know, but maybe even the lighter electrostatic protective bags for EZ Pass, circuit boards, etc. would work.

Hey All,

I use Aluminum foil to ward off the aliens stealing my thoughts, and of
course to ward off WiFi and Cellphone signals... So yeah, that should
help with the HyD detectors. ;-)

Yep,
No miracles, no aliens here. Electronics is a science of electric contacts, as we all know. It takes just one contact with out of range stray capacitance, so that with rest of the electric transmittance chain this will create a sensitive antenna (receiver) for specific radio frequencies. Purely manufacturing issue. Needs clean up from the provider.

I am a little concerned about the use of aluminum as a blocking agent here.  Not only is aluminum inert as far as magnets are concerned, but its use to block mind control waves in the radio spectrum is in fact counterproductive, as shown by a research team at MIT in 2005:

[...] According to several (apparent) students from MIT who tested several hat designs, there was "a 30 db amplification at 2.6 Ghz and a 20 db amplification at 1.2 Ghz, regardless of the position of the antenna on the cranium."

The students note that "the helmets amplify frequency bands that coincide with those allocated to the US government between 1.2 Ghz and 1.4 Ghz. According to the FCC, These bands are supposedly reserved for 'radio location' (ie, GPS), and other communications with satellites."[...]

http://www.theregister.co.uk/2005/11/11/tinfoil_hats_as_government_plot/

The original results have since disappeared from the web, suspiciously enough.  Though it may coincide with the student's personal web
page expiring when he graduated I think we can agree that the episode raises more questions than it answers.  

Cheers,

TF

I'm rather concerned with potentially trapping heat and creating noise for the detectors..hope there will be a Leica answer on this.

I think there are fine copper screens/mesh materials that would pass heat
but possibly block rf.  Think Faraday cages.

I'm rather concerned with potentially trapping heat and creating noise for
the detectors..hope there will be a Leica answer on this.

I once got locked in a confocal room because the inside door knob fell off.
The sad thing is that the room didn't have a working phone yet, nor did it
get cell reception. I had to wait for someone to walk by, get their
attention, then get them to find someone that had card key access to the
room to let me out. This happened twice. Then I started bringing a tool to
the room to reattach the door knob.

I would imagine that most people have cell phones that play music now. I
would often listen to music while on the scopes, not only did it keep me
from falling asleep in the dark room late at night, it sometimes helped
with the motion sickness scanning for cells. Cell phones are also good for
when your PI is trying to track you down and you're trying to convince him
that even though you aren't in his lab, you actually *are* doing work.

I have a related question.

How is WiFi different from cell phones?  In our institution, there is strong WiFi signal everywhere, including our confocal rooms. Would that cause similar interference??

Also, we have MDs on call using the confocals. They are obliged to carry cell phones all the time. We do ask them to not to make calls in the room, but these things are constantly receiving and sending data.

I will strongly second the idea of a Faraday cage is cell phone
signals are causing that much interference. I would even push back
against the manufacturer to demand that they retro fit the scope with
the necessary shielding. They probably won't but it never hurts to
try.

I say this because I remember back in the 90's seeing sign all over
hospitals to turn off personal cell phones because they interfered
with patient care equipment. More recently though those signs have
disappeared as equipment has been upgraded or replaced.

Back to the Faraday cage idea though: if it is effective enough to
shield the experiments looking at electrical signals of mouse muscles
then it should shield a scope from most external interference. Just
make sure that it fully encloses the components that are picking up
the interfering signals. And ground it!
