BTI bubble dosimeter mass buy

This area is for discussions involving any fusion related radiation metrology issues. Neutrons are the key signature of fusion, but other radiations are of interest to the amateur fusioneer as well.

Post by Andrew Seltzman »

Is anyone else interested in a mass buy of BTI-PND bubble dosimeters?

If you are interested, please publicly post your interest as a response to thread.

The dosimeter specs are here:
http://bubbletech.ca/product/bd-pnd/

They now also have a US distributor so you don't have to order from Canada and may be able to bypass the service fee that BTI tacks on
http://pulcir.weebly.com/bubble-tech.html

I have received some responses about people interested in dosimeters via PM, in addition to the 1 I am interested in, there are 3 more dosimeters that people are interested in. I have asked them to post there interest in the reply.

For reference prices from the last mass buy are here:
viewtopic.php?t=5954&p=39374

I do not yet know whet the current quote is.

Andrew,

I may be interested in a mass order depending on the current price and if there are a few others who join in on a group order to reduce the cost of fees.

Thanks!

Quote from Bubbletech:

"For budgetary purposes only, BD-PND list at $164 USD each. There is a two
detectors minimum order. Shipping/Handling/Insurance is extra (roughly $150
USD to your location).
Current lead time for high sensitivity detectors is roughly 4 -6 weeks."

Still waiting on quote from their US distributor.

US distributor quotes $165ea + ~$120 shipping/handling(for 2) from Canada, so about the same cost even if it's through the US distributor.

Gentlemen

Just a warning! As I rudely discovered and BTI does not make clear, the BD-PND has a useful life of only three month (with luck six) after which it is worthless and need to be discarded. Do not buy this unit expecting to put it on a shelf and get it out only occasionally for use. When the life is exceeded, bubbles present will not reset and new bubbles will not form.

The actual life varies, most people report about 6 months, though I had one that lasted years.

I'm talking with BTI about ways to reduce the shipping costs, if it's shipped on a fedex/USP account, they say you pay much less for shipping.

BTI: Our warranty for bubble detectors warrants that the detectors will be within detection performance specifications (+/- 20% of the label sensitivity) for 90 days from the date of shipping, regardless of whether the detectors are used or stored within that period of time and assuming that detectors are used and stored within acceptable conditions. The standard bubble detector storage temperature is 10 to 30 C. The standard operating temperature is 20 to 37 C. Refrigeration/freezing is detrimental to the performance of the product.

Hardly worthless after 3 months. They warrant a certain performance for 3 months, after that, a slow downhill slide in the sensitivity can be expected. Everything I've read in the past indicates most people get about a year of useful life out of them.

Still kicking around the idea of getting one. Would be nice to have one along with my He3 tube. Mostly the price and limited life have stopped me so far.

I do happen to have a FedEx account. If you want to find out how much less shipping would be, I might be up for buying one in a group. Even if I don't, I'd still be willing to let you ship it to me, and I can forward them to you. (I don't believe I can have items shipped to another address- other than what is listed on my account. I'd have to check for certain.)

The above "Discovery" announcement has been up on this site for many years now. Someone did not read the FAQs on neutron detection and the numerous other posts trumpeting this well documented BTI time limitation. Really!? They die? Yep, everyone here knew that as well as anyone reading the FAQs or casually looking over this forums postings. BTI's are great for one pass, well heeled DIY folks looking to do and prove fusion then abandon the effort upon having their name placed in the neutron club.

The super smart use of the BTI is in an intensive effort to calibrate a reliable long lived, often home made, electronic neutron counter that will be around long after the calibrating BTI is toast.

David, could you send me your shipping address for the fedex shipping quote?

Anyone who is interested, now is the time to speak up or re-confirm your interest if you still want one.

thanks,
Andrew

Sorry, busy with other things past few days and haven't checked the forum. Just confirmed my FedEx account is still active, and I can have items shipped to other addresses other than the business- so that should simplify things. I'll just pm you the account number when you need it. I'm kinda on the fence right now if I want a BD. Do you know roughly what the price would be with the savings on shipping? And then I'll make a decision w/in a day or two and let you know. Thanks.

I've decided I'm in for one bubble detector if this group buy is still on. Also wondering if you got my e-mail with the Fed-Ex info, etc.- haven't heard from you since.

Update on the quote:

I got a fedex account and the quote for shipping ff $70US, or $22 (depending if they pickup the package in Canada) for a box of
1.8 kg, 30x23x10 cm
from
Bubble Technology Industries Inc.
31278 Highway 17, P.O. Box 100
Chalk River, Ontario
Canada K0J 1J0

To Madison Wisconsin 53706

The dosimeters are cheaper then previously stated, the quote for 170 each was in Canadian dollars not USD, which is $122.15 each

Quote is attached.

That's pretty reasonable at that rate. Let me know when you need anything like info- or cash.
