Abstract
The utility model relates to a test coil for a monocoil nulcear magnetic resonance system, belonging to the field of electronic technology. The utility model is parallelly provided with the monocoil of the nuclear magnetic resonance system and can quickly test the working condition for the sending access of the monocoil nuclear magnetic resonance system or the receiving access of the monocoil nuclear magnetic resonance system. When the sending access of the nuclear magnetic resonance system is tested, the monocoil of the nuclear magnetic resonance system is communicated with current via an ejector; the sending access can induce electric voltage inside of the test coil if the sending access works under normal condition; When the receiving access of the nuclear magnetic resonance system is tested, both ends of the test coil are applied with a small signal. The working condition of the system receiving access can be judged via the condition of the system receiving access receiving the signal. The test coil for monocoil nulcear magnetic resonance system can be used for the manufacturing operation of the monocoil nulcear magnetic resonance system and also can be used for the tuning processing of a nulcear magnetic resonance device.
Description
Technical field
A kind of control coil of unicoil NMR system belongs to electronic technology field.
Background technology
When utilizing the echoed signal of unicoil NMR system test sample, can appear at the problem that does not observe echoed signal on the oscillograph.This might be that the reason of two aspects causes: the one, and start back temperature, magnetic field intensity skew, the dosage or the kind of sample change, and make the echo frequency skew and do not observe signal; The 2nd, fault has taken place in NMR system emission, reception path.If the latter, regulating frequency or change magnetic field intensity and do not have the result how again.Through launching, receive switch, tuning capacity to the monocoil current delivery of nuclear magnetic resonance path, the reception path of system comprises by nuclear magnetic resonance unicoil, tuning capacity through launching, receive the current delivery path of switch to receiver the emission path toe of system by transmitter.Whether emission, the reception path that will judge the unicoil NMR system at present fault has taken place, and the shielded box of system must be opened, and detects the quality that whether has electric current to flow through judgement system emission path on the unicoil when system transmitter is worked; Apply signal by the unicoil two ends in NMR system, the reception path of system receives the situation of this signal and comes decision-making system to receive the quality of path.
The utility model content
In order to differentiate the working condition of NMR system emission, reception path easily, avoid owing to NMR system emission, reception path fault cause waste of manpower, material resources search tuning-points, the utility model provides a kind of control coil that is used for the unicoil NMR system.Utilize it can judge NMR system emission fast, whether receive closed-circuit working normal.
The technical scheme that the utility model adopted is: in the shielded box of NMR system, along the nuclear magnetic resonance unicoil axially and the copper coil of one one circle of nuclear magnetic resonance unicoil [4] coaxial arrangement, with nuclear magnetic resonance unicoil [4] axial distance be 30～50 millimeters, be fixed on the monocoil skeleton of system, and its two ends be connected on the BNC socket on the shielded box shell that is fixed on the unicoil NMR system.When whether check NMR system emission path is working properly, can in the unicoil of NMR system, pass to transmitter current by transmitter, if the emission path normally then can induce voltage in control coil, by oscillograph by being fixed on the BNC socket that links to each other with control coil on the shielded box, can directly observe characteristics such as the amplitude of induced voltage and frequency, the working condition of their emission paths of reflection system respectively.Receive path when whether working properly in the check NMR system, can be by being fixed on the BNC socket that links to each other with control coil on the shielded box, load a small-signal at the control coil two ends by signal generator, if it is normal to receive closed-circuit working, can directly detect the signal that is added in the control coil two ends, features such as its amplitude and frequency reflect the characteristic that receives path respectively.
The beneficial effects of the utility model are, can judge easily NMR system in emission, receive path and signal and look for the problem that link such as resonance point occurs.This method is simple, can be applied in the manufacturing process of unicoil NMR system and in the tuning process of unicoil nuclear magnetic resonance equipment.
